Solar Inverters Explained
Key Takeaways
- Understand the core components of solar pricing.
- Always compare multiple quotes to find the best deal.
- Incentives can drastically reduce your net cost.
The Brains of Your Solar System
While solar panels get all the attention, the inverter does the heavy lifting. Solar panels produce Direct Current (DC) electricity, but your home runs on Alternating Current (AC). The inverter's job is to convert DC to AC so you can actually use the power.
String Inverters
A central string inverter connects a "string" of solar panels to a single box, usually mounted on the side of your house. They are cost-effective and proven technology. However, if one panel in the string is shaded and drops in production, the output of the entire string drops to match it.
Microinverters
Microinverters are small inverters installed on the back of every individual solar panel. They convert DC to AC right on the roof. Because each panel operates independently, shade on one panel does not affect the others. They are more expensive but generally provide better overall system production and panel-level monitoring.
String Inverters with Power Optimizers
This is a hybrid approach. Power optimizers are installed on each panel (like microinverters) to condition the DC power and mitigate shading issues, but the actual DC-to-AC conversion still happens at a central string inverter.
