Best solar landscape lighting for your garden or patio
Those little solar powered landscape lights that you can buy almost anywhere are convenient, and look great too. The best part is being able to add landscape lighting to your yard without having to run wiring. Just stake them into the ground wherever you want, and you’re done! Where are often aren’t so great is product quality. I’ve thrown away a lot of cheap solar lights before concluding that I needed to spend a little more money to get something that I wasn’t going to break after only few months.

What are half-cut solar panels?
Solar panel manufacturers are always competing against each other to squeeze the most power out of the same size solar panels. If you installed solar panels on your home 10 years ago, you probably had panels with efficiency in the mid-to-high teens (by percentage of light converted to electricity). Today, you can commonly find solar panels that convert more than 20% of the incoming light into electricity, with the current best residential panels hitting nearly 23% efficiency.

Solar panel kits for RV, camping, and other off-grid uses
If you like to get off the grid, whether it’s roughing it in a tent, or you’re more of a “glamper” who likes to stay comfortable in a boat or RV, you probably still like to have electricity to keep your devices powered. We’ve written articles about some of the solar technology you can use to make this happen, such as flexible solar panels, charge controllers, and solar phone chargers. However, if you have big power requirements that involve keeping a larger battery charged, things get a little more complicated.

What are the best solar panels for your home?
Are you a meticulous number cruncher who breaks out the spreadsheet whenever you’re planning a big product purchase? I certainly am. The last time I bought a car, and made a spreadsheet with the specifications of all the car models I was considering. I rank-ordered them in each of the categories that were important to me, and made my decision based on which one performed the best. Figuring out which solar panel is best for you is a little like that, although with this article I hope to make is less complicated for you.

Sungevity: a solar company back from the dead
At one point, Sungevity was the 5th largest residential solar installer in the United States. In 2017 it died (Chapter 11 bankruptcy), sold its assets, was reborn as a new company called Solar Spectrum, merged with another California installer called Horizon Solar Power, and then it brought back the Sungevity name. Along the way, it used debt and private equity to pursue a strategy of high growth - presumably to keep up with other high growth rivals like Sunrun and Vivint.
