How Does Warm Weather Affect Solar Panels?

As the weather heats up, here are some things to keep in mind about your solar panels.

Many customers worry about their panels losing efficiency in the heat. While it is true that heat affects solar panels, they don’t tend to lose efficiency until it gets above 77 °F. Solar panels have a temperature coefficient, which tells you how much efficiency decreases due to a one degree increase in temperature from the optimum temperature (77 °F). These coefficients tend to be small. For example, the coefficient of SunPower solar panels, which we often use at SGE, is -0.29%. This means that at 80 degrees, the efficiency of the solar panel only decreases by a little under 1%.

Additionally, solar panels actually keep roofs cooler. They absorb heat from the air and can make a roof up to 5 degrees cooler. The maximum temperature that many solar panels can withstand is 185°F, so there is no need to worry about them even on an extremely hot day.

At SGE, when we install solar panels, we leave some space between the panels and the roof. This allows for some airflow and keeps the panels cooler to decrease inefficiency. 

So, as long as you don’t touch solar panels on a hot day (they are very hot to the touch), there is no need to worry about your panels as summer approaches. In fact, you might even find your house and roof to be a bit cooler because of them!

Why you should make the investment in solar today

Massachusetts and Rhode Island currently hosts a variety of solar incentives for homeowners to reduce the cost of buying and installing your own solar panels. These include:

  • Net metering: which gives energy credits back to homeowners when their solar systems are producing more energy than they use in a given day. For example, solar panels often produce the most electricity in the afternoon when energy consumption is low, so net metering allows utility companies to use this energy while it is being produced, then give customers an energy credit back at the going rate that they can use while their panels are not producing. It’s essentially using the grid as a battery. 
  • SMART Solar Incentive (Massachusetts): The SMART program pays customers back a fixed rate per kilowatt hour.
  • Growth Solar Incentive (Rhode Island): The Growth (REG) Program pays customers a fixed rate at 29.6 per kWh for 15 years!
  • 26% Tax Credit: The ITC Federal tax credit was extended (two-years). The ITC for solar customers was originally scheduled to drop from 26% in 2020 to 22% in 2021 and then phase out all together after 2022. But with the recent extension, you can get a full 26% rebate back on the total cost of the system! Make sure to start the process before time runs out and schedule gets full.

Here’s other reasons to go solar for your home:

  • Drastically reduce or even eliminate your electric bills
  • Earn a great return on your investment
  • Protect against rising energy costs
  • Increase your property value
  • Boost U.S. energy independence
  • Create jobs and help your local economy
  • Protect the environment

Federal Tax Credit for 2020 and 2021

Did you know the Federal Investment Tax Credit is Phasing out! This is the most significant financial benefit for going solar. As a turn-key installer, Second Generation Energy will manage the process of getting your solar system installed so you can take full advantage of the 26% Federal Tax Credit WHILE YOU CAN.

Changing Energy Economy

More people are deciding to go solar every year. Going solar will reduce or eliminate your electric bill, earn a good return for your investment, increase your property value, protect against rising energy costs, and protect the environment by cutting your consumption of non-renewable energy.

As the demand for solar and other types of clean energy jobs increases all over the country, blue-collar jobs in the field are booming. Forbes magazine states that over time it will become less expensive to build new renewable energy than run existing coal plants without. The construction and operation of new renewable energy plants that replace coal is the newest progressive transition in the energy economy today. The U.S. Bureau of Labor Statistics forecasts that the two fastest growing in 2026 will be solar installer and wind technician.  The increase in green jobs is happening in both red and blue states. The American Wind  and Energy Association posted a map (https://thumbor.forbes.com/thumbor/960×0/https%3A%2F%2Fblogs-images.forbes.com%2Fenergyinnovation%2Ffiles%2F2019%2F04%2FCongressional-District-wind-industry-footprint-1200×932.jpg) of congressional districts with online wind projects and wind-related manufacturing facilities.

Coal jobs however are in a general decline from 86,000 in 2009 to 52,000 in 2018 (with small 2,000 increase due to President Trump’s efforts between 2017-2018). This changing market economy has led to dozens of coal plant closures in 2017, with a 4% drop in coal consumption in 2018 and 8.4% drop in consumption in 2019. Many areas int he US see a general decline in cost of renewable energy, though in some areas the cost of it might not yet be below coal. VCE Energy Innovation produced a map (https://blogs-images.forbes.com/energyinnovation/files/2019/04/Coal-MCOE.gif?) forecasting this disparity visually for wind and solar systems. It shows that these systems may be cheaper than coal energy more-so in the eastern half of the country and in south-western states, with some difference in the center of the nation as well. This may be due to more sunlight exposure and wind energy capacity in these areas. In places with still a higher forecasted cost of renewable energy than coal we know coal is a major industry, like near the Mexican Gulf and in the north-west. This map is not necessarily complete and still misses detail, but it could indicate further geographical disparities in production of wind and solar energy by 2025.

According to Brookings Institution research, clean energy jobs are commonly available to people without college degrees, like 45% of all workers in the clean energy production industry doing electrical work, installation, repair, and plant powering. The institute took Occupational Employment Statistics data in 2016 to show that the mean hourly wage in the clean energy jobs market in higher than the national average mean hourly income by about 8%-19%.

Solar Star

Solar Star farm in Kern County, California.

More people are deciding to go solar every year. Going solar will reduce or eliminate your electric bill, earn a good return for your investment, increase your property value, protect against rising energy costs, and protect the environment by cutting your consumption of non-renewable energy.

Sometimes solar panels can be truly awe-inspiring. In addition to community solar there are many enormous solar fields around the world, including Solar Star, America’s largest solar farm and the world’s largest when it was created in 2015. Solar Star spans over 13 kilometres squared, about four times the size of central park. It produces 579 megawatts of energy, and powers over 250,000 homes, and you can see it from hundreds of miles above the ground!

Located in Kern and Los Angeles counties in California, it was built on “disturbed” land, meaning land that was already altered by people and not in its natural state. These panels get cleaned in a way that uses minimal water, and automatically follow the sun’s motion across the sky, which makes them more efficient. According to Solstice, these panels impact the environment as if they took 108,000 cars off the road every year! Additionally, the project was reported to have created 650 jobs over three years, and 40 maintenance jobs through its lifetime. The panels are also a source of pride and leadership for the US renewable sector.

Mega-scale solar farms are becoming more common around the world. Since 2015, solar plants in Mexico, China, and India are all projected to reach a range of 1,000-2,000 megawatts soon. The UAE even plans on building a plant with 5,000 watts by 2030. Back in the US, there are other large fields too, like the Desert Sunlight and Topaz farms producing 550 megawatts each, but they take up more space. Solar energy is becoming more affordable for the average American to place on their properties and commercial buildings every year too. More efficient benefits of distributed energy generation and more resistance to outages for small-scale projects should keep getting better, making more numerous small-scale projects across our communities It brings more affordable energy to people across the country and thus helps us life more cheaply.

Still, we will keep our eyes out for updates on the production of these mega farms in the US and around the world. The solar industry creates many jobs for people for farms of all sizes and contributes to maintaining a clean planet and reduction in carbon emissions. The solar industry is growing exponentially, with an almost 200% increase between 2016 and 2017, and 2,056 megawatts of community solar has been installed in the US through 2019! It brings better energy to people across the country, including in Massachusetts, Rhode Island, and Connecticut, which Second Generation Energy serves.

 

Solar Efficiency in Cold Temperatures

Solar photovoltaic (PV) panels create energy from the sun’s radiation “sunrays” & not from the sun’s heat. A solar panel is made up of a layer of silicon cells and when light interacts with a silicon cell, it causes electrons to be set into motion, which initiates a flow of electric current.

When the sun is hitting a solar panel, the solar panel will generate electricity — no matter how cold it is. Most people don’t know that solar works more efficiently in colder temperatures. A sunny and cold environment in New England is the best condition for solar panels. Heat actually reduces solar efficiency (tests shown that panels start to lose efficiency above 77ºF).

Best example is the McMurdo Station, the primary hub for U.S. science operations on Antarctica, using solar as it’s critical source of power. Temperatures in outer space, where solar powers the International Space Station, experience the most extreme cold temperatures that are significantly colder than New England winters or even Antarctica’s tempatures!

In fact, the solar industry is thriving in cold-weather states like here in Massachusetts (our main office location), Rhode Island and Connecticut.

This isn’t to say that solar is better or produces more energy during the winter months. Shorter days in winter, snow cover, clouds and a lower angle of the sun can all reduce the amount of sunlight solar panels get.

Rhode Island Solar Guide

About the RI Office of Energy Resources Solar Guide

The purpose of this guide is to assist Rhode Island residents who are considering solar energy to generate electricity in their homes. This guide will help determine whether a solar PV system is right for you. It reviews solar PV technology, the installation process as well as available incentives. This guide focuses on solar systems interconnected to the utility distribution system. While this guide is intended primarily for homeowners, many of the issues discussed apply to small scale installations in general and may apply to businesses considering solar.

Why Go Solar?

In 2018, Rhode Island was the 8th most expensive state for electricity in the country.  In that year, natural gas fueled over half of the electric power sector and nearly all in-state electricity generation. Solar can help reduce reliance on natural gas and cheapen the cost of electricity.

SGE – SunPower panels

SunPower Corp on Tuesday said some of the solar cells and panels it produces overseas will be excluded from the Trump administration’s 30 percent import tariffs, sending the company’s shares up 15 percent.

SunPower is based in San Jose, California but produces most of its solar products in Mexico and the Philippines. The company has publicly lobbied for its products to be exempt from the tariffs, arguing the funds it was spending on duties were being diverted from investments in American jobs in research and development and domestic manufacturing.

The exemption covers SunPower’s premium, high-efficiency interdigitated back contact (IBC) cells and modules, which the company argued stood apart from the cheap, commoditized imports that dominate the market and were the target of the tariffs.

“With today’s decision that SunPower’s highly differentiated IBC cells and modules are excluded from tariffs, we are able to turn the page,” SunPower Chief Executive Tom Werner said in a statement.

U.S. President Donald Trump in January announced a 30-percent tariff on all imported solar panels, an opening salvo in an escalating global trade dispute he said was aimed at helping U.S. manufacturers and other businesses rebound from years of decline. Much of the U.S. solar industry protested the move, saying it would chill one of America’s fastest-growing sectors.

SunPower, which earlier this year agreed to buy a U.S. solar manufacturing facility in Oregon from SolarWorld Americas to expand production in its home market, said the deal would close before the end of this quarter.

SunPower said the decision by the U.S. Trade Representative to exempt some of its products from tariffs would be published in the Federal Register on Wednesday.

SunPower shares were up $1.01, or 15 percent, at $7.59 on the Nasdaq. SunPower is majority owned by France’s Total SA .

Critter Guard

You made a great decision in going solar and your solar panels are an excellent investment.  In order to protect your investment, you will want to pay close attention to what may be going on under and around your solar panels.

As we enter into the summer months, we typically see an increase in bird and critter activity, especially if your home is near trees or overhead wires. Rooftop solar panels create an ideal environment for pigeons and other birds to nest and roost.  The panels provide shade from the hot sun and a sense of security from predators.  Also, squirrels can be notorious for nesting under rooftop panels and can possibly chew through exposed or hanging wires. They may use their teeth to cut power lines to and from solar panels and, if they chew the right wire, this could lead to expensive and unwanted repairs.

If you notice an increase in bird and squirrel activity around your home, it’s critical to check and make sure they’re not nesting underneath your panels.

In most cases, you won’t need Critter Guard, but if you do see squirrels or birds in or around your system and want a high strength screen around the panels then call us today at 508-377-4037 or email us at info@sgegroup.com  for a Critter Guard quote.
