There are several solar technologies in the market - microinverters, string inverters, and string inverters with DC optimizers. It is important to understand the differences and details of each to make the right choice.
The state where your project is located lets us estimate your utility rate and the amount of sunshine at your site.
Select the total size of the solar system in kilowatts DC. It is the module power multiplied by the total number of modules.
Select the DC output power rating in watts DC for the modules under standard test conditions.
The cost for the string or central inverter(s), assuming no extended warranty. The national average cost is $.15 / W for non-residential systems. Learn more.
The total installed cost for the entire solar system, including materials, labor and overhead. The national average cost is $2.25 / W for non-residential systems. Learn more.
It’s the distributed architecture advantage: without a single point of failure, microinverters make for a more reliable system. You’ll never have to worry about one mishap crippling your output. Plus, all-AC power means greater safety.
Without the rigid design limitations of conventional inverters, you get simpler, faster engineering, even on typical roofs. Forget finding space for a string inverter or large setbacks around obstructions, and maximize the density of your array.
