Solar panels produce DC electricity, and the inverters convert the DC electricity the solar panels produce into AC electricity we use at homes and businesses. The ratio of DC power connected to an inverter and the maximum amount of AC power an inverter can produce (or inverter rating) is called the DC-to-AC ratio. E.g., When a 12 kWdc solar panel array is connected to a 10 kWac rated inverter, DC-to-AC ratio is 1.2 (12kW/10kW).
Since solar panels are rated at standard test conditions, solar panels reaching peak power do not occur occasionally under normal operating conditions. Hence, it makes sense to oversize a solar array, compared to inverter rating. It means, the DC capacity divided by the AC rating is greater than one. This results in a greater energy harvest when production is below the inverter’s rating, which typically happens for most of the day.
However, when the solar array produces the most solar energy at a level higher than the inverter’s power rating, the extra power is “clipped Upgrade ” by the inverter. This is called inverter clipping which ensures the inverter is operating within its capabilities but results in lost energy production during peak production hours. So, when selecting an inverter for a solar power system, it is important to consider how much DC power the solar array will produce and how much AC power the inverter can output.
The maximum oversizing ratio of an inverter depends on number of strings connected the inverter, connected string size, inverter efficiency and factors that affect the inverter’s operating temperature and inverter’s ability to cool, such as shading, mounting and elevation.
The economical limit of oversizing a system can vary, but most projects have the same goal of optimizing the levelized cost of energy. ABB, an inverter manufacturer did a series of studies to find a safe limit for DC-to-AC ratios using its inverters. ABB found that the optimal DC-to-AC ratio in these areas depended on the design goal. For example, regardless of site conditions, sizing a system to maximize specific yield allows for an ideal DC-to-AC ratio at or slightly below 1.2. However, sizing a system to target the best financial output could lead to higher DC-to-AC ratios, between 1.3 and 1.6.
Having a larger array on a fixed-size inverter results in greater annual system production, while fixed system, permitting, interconnection and other costs stay the same, shifting financials in favor of a higher DC-to-AC ratio. Credit:ABB
Nowadays, people have developed a sense to save resources by utilizing nature’s energy like wind energy, solar energy, water energy, and more. In this modern landscape, solar energy for homes has reduced the revenue pools of private electricity transmission and distribution companies. Now, the solar energy can be used to charge the batteries that can power up many electrical appliances of the house.
The solar powered generator Thorn Hill is not only good for the environment but also can serve as emergency power backup. Previously, people used to charge their inverter batteries to take the benefit whenever there is power loss. This charging of inverter batteries consumes kilowatts of power units that get added to your electricity bill amount or to generate electricity you have to fuel electricity generator with kerosene that is again an expense. The combustion of kerosene pollutes the environment to great extent. But, now with the advancement of technology things are completely changed, you neither have to wait for the generator to get started nor you have to pollute the environment as solar power generators are fueled by solar energy.
Whenever there is thundering or rainfall, power cut-off is no more a hassle as to illuminate the darkness solar power generators are available in the market. The solar devices get charged by the sunlight and deliver the electricity to your household appliances. The major benefit is that you can connect solar powered devices together to deliver more electricity. Its demand is increasing by leap and bound every year and soon it will become every house needs.

In the recent year, it has been noticed that the utility of electricity has been increased. Many new companies are coming up in the market and the new residential buildings are constructed for the person, which leads to more electricity requirement. The generation of electricity makes the environment polluted because the electricity generation includes burning of coal, fossil fuels, and much more. This brings up a lot of air pollution. Therefore, to keep the environment green and clean Solar Installation in Vaughan is the silver bullet. You can save cost on energy by installing the solar panels at the top of the buildings. On the other hand side, the installation of solar cells will cut the cost of paying electricity bill to the private power generating firm. The solar panels have the transducer that converts one of the forms of energy into another form through the sensing device and connected circuit. So, this way the transducer converts the solar energy of the sun into electrical energy that supplies power to the electronic appliance of commercial or residential verticals.

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 • Economical • 8 – 20 hours to charge a fully discharged battery • Portable • 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.
Level 2: 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: 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.

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.
