After many years of development and political debates about solar energy, the solar industry is finally approaching to stand on its own. Utility-scale solar power projects worldwide are beating fossil fuels on price without any subsidies; commercial, industrial, and residential projects are also approaching grid parity.
Solar energy is the most abundant energy on the planet. Solar energy hitting the earth every hour is enough to meet all of humanity’s energy needs for an entire year. If we could capture one hour’s worth of solar energy each year, we do not need any oil, coal, and natural gas. And the earth will become a lot cleaner and brighter.
Solar panel costs have fallen from $77 per watt in 1977 to the current price, an almost 100% reduction. Electricity generated at a utility-scale solar plant costs as little as 4.3 cents per kWh on an unsubsidized basis, less expensive than every option for new fossil-fuel power plants.
Solar power plants can last 40 years or more and require minimal maintenance. Solar panels come with 25+years of warranty. If needed can be easily replaced with new, more efficient modules at a relatively low cost.
Solar dominate the new generation capacity installed around the world. As solar becomes cost-effective, a big part of new power generation plants is solar. As costs come down, more utilities look for solar assets, and solar will further dominate the new generation capacity additions.
Solar is the fastest energy source to deploy. No electricity source can be built or repaired as quickly as solar. No other power plants, fossil-fuel or any other renewable energy plants, could be constructed rapidly as solar plants.
Big utility-scale solar power plants built-in in remote areas get a lot of attention in the media. But the distributed rooftop solar is disrupting how we look at energy. Rooftop solar projects are spread all over the grid, from home rooftops to panels installed on your local big-box retailer. There is probably a solar panel system near you.
If you want to go solar, a rooftop system is the best choice for you. But even if you don’t own a home that is suitable for installing solar panels, you can get 100% of your electricity from solar energy from a growing number of places. Community solar projects allow ordinary consumers to invest in their solar projects and purchase their solar electricity through a power purchase agreement. Energy distributors give customers the option to source their electricity from wind or solar for an extra fee.
The bottom line is that solar is booming worldwide, and the trend shows no signs of slowing down. Every energy consumer should notice this change and embrace the emerging clean and bright energy future.
The popularity of electric vehicles is growing in Canada and around the world. EV sales have been growing by more than 25% year over year and Tesla motor company’s value has become larger than that of GM and Ford car companies combined.
It is estimated that more than 120,000 EVs currently on our Canadian roads lead to the increase of the demand for convenient and accessible charging stations. Hotels and other businesses are starting to offer EV charging stations to increase their customer base. EV charging stations are popping up at malls and stopovers along major highways across the country.
If you’re thinking about installing an EV charger at your home or business, New Dawn Energy Solutions Team is here to help you. EV charging capacity you can install will depend on the EV and the electric service size at the property where you want to locate the charging station. With so many EV chargers and NEEMA plugs to choose from, we will help you choose the right one for your needs.
EV chargers are grouped into three levels – Level 1, Level 2 and Level 3 chargers.
Level 1 Charger:
Level 1 EV chargers are mainly rated at 120-volt 15A hence it can be plugged into any standard outlets.
• Popular in households
• 8 – 20 hours to charge a fully discharged battery
• Slowest speed of charging – charges 8 km per hour
These chargers are portable and don’t require special installation. The downside is slow charging, takes anywhere from 8 – 20 hours to fully charge an EV battery from a fully discharged state. If you don’t drive long-distance every day and can find plugs where you go and have time to plug-in, a Level 1 charger may be right for you.
They are much faster than Level 1 chargers as they are connected to a 240-volt outlet – just like a clothes dryer or an oven. As Level 2 charger requires new infrastructure in the garage, an electrician is needed to install safely and efficiently. If you regularly drive long distances and don’t have a lot of time to recharge, the Level 2 charger may be a necessity.
• 240-volt power
• 5 -10 hours to charge a fully discharged battery
• Installed by a certified electrician
• Popular in industrial, commercial, hospitality and residences • Charges 30 km per hour
Level 2 chargers are the most common and have become the standard for most drivers’ needs.
Level 3 EV chargers, or DC fast chargers, are found mostly at commercial, industrial, institutional properties and along major highways in Ontario.
• 480-volt power
• Charges 100 km per hour
• Used mostly in businesses and public areas
• Fastest charge – 20 mins to charge a fully discharged battery
Level 3 chargers aren’t as popular as Level 1 and 2 because of the voltage they operate, higher price tag and installation requirements. If you’re a business that caters to drop-in customers such as a rest stop, restaurant or retail store, having a Level 3 charging stations can put you a step ahead of the competition.
With more EVs on the road and battery life continue to improve the selection of chargers will increase too. The current range of an EV is about 500 km, but over the next few years, it is estimated the driving range to increase to 700-750 km per charge.
There are several EV charging manufacturers in the market space and each comes with their own features, benefits and price points.
When comparing the overall cost of an EV to a standard gas or diesel vehicle, there are many benefits and long-term savings. Because of their zero emissions and lower maintenance costs, EVs are going to be a part of the future of transportation.
If you want to learn more about EV chargers or aren’t sure which charger is right for you, contact New Dawn Energy Solutions today, one of our trained specialists can help find the right EV charging solution for you.
To stop global warming and dangerous CO2 emissions we need to put coordinated and concentrated efforts in every part of the society- government, business, and the community. This includes all of us as homeowners. As homeowners, we can play a major part in keeping our planet green by getting smart, going solar and reducing our collective carbon footprint.
Today’s smart homes have energy-efficient appliances connected through the internet and you can turn on your light and heat before you reach your driveway and check on your kids from work. You can water your yard from another country. But to do all these your home needs energy and a solar system plus battery storage can provide you with that energy.
Air conditioning our homes takes an enormous amount of energy and dollars – not to mention keeping other appliances running when we need them the most. Our grid structures are failing,6 and many grids can’t handle increased power demands on a hot day.
New Dawn Energy can help to boost energy efficiency in your home and businesses. Our solar+battery system is optimized to give you control over your power usage. This means you get to see how much energy you use real-time and decide when and where the lights stay on.

The lead-acid battery has been around for over 100 years that costs less, requires regular maintenance to keep them working properly and doesn’t last as long.
Lithium-ion battery relatively newer technology with a longer lifespan, high power density, higher efficiency, does not require regular maintenance but costs more.
Both technologies are affected by discharge cycles, Lithium-ion has a significantly higher cycle life than lead-acid in deep discharge applications such as in solar. This disparity is further increased as ambient temperatures increase.
The cycle life of both chemistries can be increased by limiting the depth of discharge (DoD), discharge rate, and temperature, but lead-acid is generally much more sensitive to each of these factors.
In hot climates where the average temperature is 33°C, the disparity between lithium-ion and lead-acid is further increased. The cycle life for lead-acid (flooded and VRLA) drops to 50% of its moderate climate rating while lithium-ion will remain stable until temperatures routinely exceed 49°C.
Another critical consideration for lead-acid is how long the system will take to discharge. The shorter the discharge period, the less capacity is available from the lead-acid battery. A 200Ah lead-acid battery will only deliver 120Ah if discharged over a one hour period. In contrast, a 200Ah lithium-ion battery system will achieve over 184Ah. This condition makes lithium-ion very well suited for applications where full discharge occurs in less than eight hours.

With extreme weather events and other threats to energy security increasing homeowners and businesses are contending with the danger of losing access to reliable power supplies. Beyond emergency scenarios, unexpected blackouts during day and nights also increasing in numbers and durations.
It is estimated an hour of energy downtime costs companies from thousands of dollars for small companies to millions for large companies. Homeowners are also exposed to economic losses, which can be further worsened by dangers to family health and safety. Energy can storage plays a central role in the design of reliable backup and emergency power systems that protect homes and business operations when power is intermittent or completely unavailable.
According to the needs and affordability, homeowners can choose a backup system to back up critical loads like the refrigerator, a home medical device, a computer, cell phone charging, lights and the HVAC system using a subpanel, or entire home load using large battery bank. Many businesses also require back up of mission-critical systems such as servers, payment systems, refrigeration, and communications. Depending on their operations some businesses may need power for critical power for multiple days.
For customers who already have a diesel generator for backup power, integrating storage with generators reduce the number of hours generator need to run and the gallons of fuel they need to burn. In this scenario, the generator becomes a battery charging supply rather than a primary power source. Optimizing generator operation this way delivers a 50-80% savings in fuel and dramatically reduces noise, toxic pollution and increase energy security.
Among the battery technologies, Lithium-Iron Phosphate (LFP) have high efficiency, safety rating and low levels of self-discharge over time. This can play a key role in cutting diesel consumption by storing energy for a longer duration without degrading or losing power until that time that an end-user needs it.
Solar customers also benefit from storage during the plan and unplanned grid outages. Rather than shutting down the inverter when the grid goes down, batteries and the inverter charger enable homes and businesses with PV systems to ‘island’ from the grid and retain access to their own generation by creating a mini-microgrid for as long as the grid is unavailable. Depending on the requirements, battery banks can be sized to keep homes and businesses up and running safely and securely over the course of multiple days.

You may not think much about your electric bill payment every month. And if you do, you might think that is just the cost of living / doing business, right? Not exactly. Take a moment to think the energy you are likely paying for that room in your home/office no one ever uses, and you’ll definitely want to learn how to avoid these to reduce your energy costs.
By following simple steps to increase the energy efficiency at your businesses, you can lower your electric bill by hundreds to thousands of dollars every month. Here are a few simple changes you can make that can add up to short-term and long-term energy savings.
1. Get an energy audit
Energy audits can help you figure out where your money is going every month, how to increase energy efficiency and how to lower electric bills.
2. When not in use, turn off lights and equipment
This sounds very obvious, but you will be surprised to know many people do not do this and the amount of energy all those computers, monitors, printers and other devices consume while sitting there unused but still left on. By making sure they are in “sleep mode” or turned off completely overnight, you will not be paying for electricity you are not even using. One tip is to plug all these energy hogs into a single power bar, so you can turn them off at the same time on your way out the door. Also, make it someone’s nightly routine to take a quick tour of the offices and flip the OFF switch on idle equipment.
3. Take advantage of natural sunlight as often as you can
Let the sunshine in! Open the blinds around to make the best use of daylight—and take advantage of skylights or other natural light sources to reduce your lighting needs during daytime hours.
4. Install long-lasting LED bulbs
Replacing a single 60-watt incandescent bulb with an 8-watt energy-efficient bulb that is on for 10 hours a day can easily save a $1 or more each month. Multiply that out to an entire year—and by the hundreds (if not thousands) of bulbs in your business—and you’re talking about some serious savings. LED light bulbs not only use at least 75% less energy, and they also last 50 times longer than the average incandescent—up to 20 years – reduce the maintenance cost.
5. Use motion detectors and automatic dimmers that adjust to your needs
Lighting accounts for almost 20% of the electricity used in U.S. commercial buildings. Hence being a little bit smarter about when, where and how you use the lighting in your building(s) can add up to big savings. Consider installing motion detectors in hallways, meeting spaces and other places where “always-on” isn’t always needed—along with automatic dimming controllers that measure and adjust to the light levels you actually need.
6. Install programmable thermostats, and use them wisely
A programmable thermostat gives you the power to automatically adjust the temperature of your workplace when no one’s there. Set yours to turn the AC or heat on 30 minutes before people arrive and off 30 to 60 minutes before they leave. In warmer weather months, it’s a good idea to set your thermostat no lower than 78 degrees during office hours in order to reduce energy use. Then, during cooler weather periods, set your thermostat no higher than 68 degrees.
Keeping your office temperature just 1-degree cooler during winters and 1 degree warmer during summers can reduce the power you use by up to 10%!
7. Keep the heat in or out with screens, film and weather-stripping
While you might think that gentle breeze from your room window isn’t a big deal, it’s really money and energy flying right out the building—and it’s too easy a fix to ignore. Add or replace weather-stripping, caulk or foam around your windows and doors to save energy. Windows also let in the sun’s light and heat, which can make it more expensive to cool your office in warmer weather. Luckily, there are plenty of window treatments that can help you to reduce heat gain and increase energy efficiency, including solar screen window shades, awnings and high-reflectivity window films.
8. Purchase energy-efficient office equipment
When you need new equipment/appliances, be sure to look for the Energy Star logo. Energy Star-labeled fridges, washers, dryers, computers, monitors, printers, fax machines, scanners and copiers can run much more efficiently and automatically power down during extended inactivity. That can help you save 50% or more in energy use on these power-hungry devices. And, if your old heater or air conditioner is not working at maximum efficiency, it could draw unnecessary power, which also costs you money. Replace any old heaters and AC units with Energy Star models.
9. Consider alternative and renewable energy sources to help power your business
Using commercial renewable energy sources, such as solar and small wind, to power some or all of your business can help lower your business energy costs over time. Doing so also generates power that’s free of harmful CO2 emissions and other greenhouse gases. Based on a number of factors, there may never be a better time to invest in solar (or other sources of clean energy) to get the energy your business needs while paying less over the long term.
10. Keep your HVAC systems running smoothly
Change the filters on your HVAC equipment regularly, and make sure to have the units inspected and cleaned as often as recommended. Keep the areas in front of all vents clear of furniture and paper. As much as 25% more energy is required to distribute air if your vents are blocked.

An inverter is the most critical component of a solar power system. A grid-tie inverter performs many functions than any other component in a solar power system. The functions an inverter need to perform continue to grow as the solar power systems get smarter and increase interaction with the utility grid.
Here the key functions a grid-tied inverter perform
Power conversion from AC – DC
The main function of an inverter is power conversion – convert the direct current (DC) power that solar panels generate to alternating current (AC) power that is normally used in homes and businesses or fed directly into the grid in case of a utility-scale solar power system.
Maximize power generation
Inverters continuously track the solar array’s voltage, current and identify an operation point to generate the maximum power from the solar array.
Interface with the grid
Grid-tied inverters have advanced from one-way communication to two-way communication with the grid and assist with grid-support functions. With advanced software, smart grid-tied inverters can perform grid-supportive functions related to voltage, frequency, communications, and controls.
Monitor the function of the solar power system
Inverters make it possible for solar owners to keep track of the power output of their solar systems. Most inverters have communications capabilities via hardwired ethernet, Bluetooth or Wi-Fi. Through this communication connectivity data stored in the inverter is uploaded to a monitoring portal which in turn enables solar power system owner, installers to monitor the performance of the solar power system and take appropriate actions proactively.
Ensure safe system operation
An electrical arc can cause fire hazard and material degradation. Grid-tie inverters are programmed to identify these arcs and shut down the inverter to enable safe operation.
Inverters are made up of many electronic components and perform numerous tasks, they are more likely to fail than other components of a PV system. Micro. string and central inverters come with different pros and cons, but string inverters are more easily serviceable when a failure happens.
If you are thinking of what kind of inverter to use with your solar power system and how much it would cost complete the Free solar Assessment request at our website or give us a call at 416-855-9377 we will guide you every step of the way.

Adding a battery to your existing solar power system is not always an easy task. If your solar power system was installed storage-ready, adding the battery could be easy but with the rapid advancements of solar-plus-storage in the last few years, it is unlikely many old solar systems can easily accommodate battery connection. But that does not mean it is impossible; there are just a few important questions you must answer before starting a retrofit solar-plus-storage installation project.
What is your inverters make and model?
The inverter used on an existing solar panel system will dictate how a battery can be added to an existing solar power system. Solar-plus-storage systems are either AC-coupled or DC-coupled. AC-coupled systems require an additional, separate inverter to charge the batteries. DC-coupled systems use a charge controller to feed the power from the solar array to the batteries and then through an inverter for grid-tied use. For example, existing systems with microinverters which make the DC-AC conversion at the panel-level will need an AC-coupled system for storage, since the battery cannot be incorporated into the DC lines before AC-conversion.
To accommodate energy storage in an AC coupled system, existing grid-tie inverters must have frequency control capability. If the existing older inverters cannot frequency shift, they should be replaced to add batteries. Adding new inverter that can regulate charges is the only way to include storage on this type of existing solar PV system. Inverters are usually warrantied to 5 /10 years. If the inverter is approaching its warrantied lifespan, it’s a good idea to upgrade. It may be advantageous to replace the inverter with an inverter designed to accommodate storage to enable options to integrate storage immediately or in the future.
Why do you want to add storage?
Another question to answer – is your storage solution for emergency power? Or to store excess energy produced by solar during the day, so that it can be used in the evening when the sun goes down? Or in places with a TOU tariff, charge the batteries with solar or grid power when rates are cheap and discharge the batteries when power is most expensive. Depending on your objective, it is important to have an inverter that allows for your specific storage need and an appropriately sized battery bank to support your power needs.
Who owns the solar system?
Another question to answer – is your existing solar PV system owned by you or leased? If you have full ownership adding storage is easy. If your existing solar panel system leased it may have restrictions on adding certain equipment. Typically leased solar power systems have a wide range of restrictions as to what changes can be made to the home or business and its electrical loads. Adding energy storage may be prohibited by lease terms.
