Comparing efficiencies for AC vs DC-coupled batteries

As is the case with comparing solar panels and inverters, when comparing solar batteries, there are a number of different technical specifications that differentiate one battery from another: power ratings, usable energy capacity, warranties throughput or cycles, start-up power, and the efficiency of the battery. Unlike solar panels and inverters, though, the stated efficiency of each battery is not necessarily directly comparable to the efficiency of other batteries. Here’s why:

Have you ever come across “flexible solar panels,” or “stick-on solar panels”? Both fit under the wider umbrella of thin-film solar panels, which is a type of solar panel technology known for being lightweight. Compared to traditional solar panel cells, thin-film solar panels are made up of electricity-producing layers that are hundreds of times thinner than typical silicon cells.

Last week, EnergySage released our eleventh Solar Marketplace Intel Report. The free, publicly available report provides insight into the state of the solar market nationwide and at the state level through July of 2020. In this report, we take a look at the impact of the coronavirus pandemic on the solar industry, check in on how solar pricing compares on EnergySage to data from the rest of the market, and introduce a few brand new analyses of energy storage data, from cost to brand preference. A few key takeaways from the report are outlined below, and we look forward to your analysis and feedback on the report.

Should you cut down trees to go solar?

When we talk about the environmental benefits of solar power, we often compare the overall carbon offset of a solar panel system to the environmental impact of planting trees. Ironically, maximizing the benefits of solar power may mean cutting down a tree or two prior to installation.  It’s a difficult truth, but unfortunately, solar power and trees don’t really get along. Branches and leaves can block sunlight from hitting your roof, which means your solar panels aren’t generating as much clean electricity as they could otherwise be in a sunny area.

Solar panel cleaning: what you should know

Your solar panels need to be exposed to sunlight in order to produce power. However, unless you live somewhere with high amounts of smog, dust, dirt or sand blowing around, solar panel cleaning is generally not necessary. In most cases, occasional rain will be enough to naturally and safely keep your solar panels clean and free of debris that could lower production.

It may be a good idea to freshen up your panels occasionally if you live in an area with heavy particulates in the air. Here are answers to some of the top questions solar panel system owners have about cleaning solar panels and how to do it safely.
