On average, homeowners pay between $2.50 to $3.50 per watt installed. For a typical 6 kW system, this comes out to approximately $15,000 to $21,000. DIY Solar Panel Cost: Is It Cheaper? If you’re handy and have some technical know-how, you may consider building your own system. [pdf]
[FAQS about How much does it cost per watt to buy solar panels yourself]
There are three types of inverters available: the string inverter, the power optimizer, and the micro-inverter. You would only need one inverter when using string or power optimizers, but using micro-inverters doesn’t require a standalone one. .
You would need to purchase an inverter that matches the output of your solar array, so if you have a 6000W (6kW) system, your inverter would need to a rated at 6000W. You. .
You can connect inverters in parallel to double the wattage (power) or in series to increase the voltage. You could do this if you have several smaller inverters that you want to connect. [pdf]
