String Inverter vs Microinverter vs Power Optimizer: Which Is Best For Solar?
String inverters cost $1,000–$2,500 but shade on one panel kills the whole string. Microinverters cost $150–$190 per panel but each panel operates independently with a 25-year warranty. Power optimizers fall in between. Full 3-way comparison with efficiency data, cost breakdown by system size, sizing guide, and grid-tied vs hybrid vs off-grid explained.

Solar installation takes 1–3 days of physical work but 6–12 weeks total (permits + utility approval). Professional installation costs $2.50–$3.50/W installed. DIY saves 30–50% but requires permits and a licensed electrician for grid connection. Step-by-step process, roof mount vs ground mount, mounting by roof type, permits, timeline, and DIY pros and cons.
