Most of the solar panels that are installed in the United States are made of silicon photovoltaic (PV) cells, but silicon PV doesn’t work for every situation. Thin film solar panels are an alternative that’s starting to take hold, particularly in situations where rigid PV panels aren’t an option.
There’s a lot of buzz around Boston-based Sistine Solar, and for good reason: their product allows homeowners to customize how their solar installation actually looks on the roof of their home. Sistine Solar’s innovative new solar technology is designed with the aesthetically-focused solar shopper in mind.
In February 2018, Tesla announced a partnership with home-improvement giant Home Depot to sell and promote Tesla Energy solar installations. As a result, we’ve been receiving lots of questions about the new Tesla Home Depot partnership from shoppers on the EnergySage Solar Marketplace.
Through the partnership, Tesla will be setting up large displays of Tesla Energy products so that shoppers can see them up close in about 800 stores across the country. Displays will be staffed with Tesla Energy employees to answer questions and talk to shoppers about installing solar.
On January 22, 2018, the Trump Administration announced a 30 percent tariff on solar panels and cells imported into the United States. This announcement raised a lot of questions for solar customers on the EnergySage Solar Marketplace. One of the most popular questions: where can I find solar panels that are made in America?
Kyocera is one of the world’s oldest solar panel manufacturers, and has manufactured solar panels since the early 1980s. The electronics company manufactures its solar products in Japan and China, and is one of the most popular brands featured in quotes to solar shoppers comparing their options on the EnergySage Solar Marketplace.
Power output or wattage is an important factor to consider when comparing solar panel options. You may hear your solar installer say, “it’s a 255 Watt panel” or “the panel I am recommending is has a wattage of 300.” Or, when you are reading a quote from a solar installer, you might see numbers like 245W, 300W, or 345W next to the name of the panel. They are all referring to a solar panel’s wattage, capacity and power output.
How much energy can a solar panel produce?
Available sunlight will vary depending on where you live but for the sake of an example, if you are getting 5 hours of direct sunlight in a sunny state like California you can calculate it this way: 5 hours x 290 watts (a wattage of a premium solar panel) = 1,450 watts or roughly 1.5 kilowatt-hours (kwh). Thus each solar panel in your system would produce a little over 500-550 kWh of energy per year.
All solar panels are rated by the amount of DC (direct current) power they produce under standard test conditions. Solar panel power output is expressed in units of watts (W), and represents the panel’s theoretical power production under ideal sunlight and temperature conditions. Most home solar panels on the market today have power output ratings ranging from 250 to 400 watts, with higher power ratings generally considered preferable to lower power ratings. Pricing in solar is typically measured in dollars per watt ($/W), and the total wattage of your solar panels plays a significant part in the overall cost of your solar system.
Who are the top solar companies in the world and in the USA?

Tesla’s plans to make solar panels have been known for years. The company is constructing a factory in Buffalo, NY, specifically to produce Tesla solar panels, but until recently not much more was known about their plans.
In April 2017, the much-discussed solar panel product was finally revealed, but the company didn’t announce it with the fanfare usually reserved for Tesla product releases. Instead, the Tesla Energy website was quietly updated to include a page specifically dedicated to solar panels alongside its other energy products like the Powerwall and Tesla solar roof.
