Solar for a $200/Month Bill — FAQ

How does shading affect solar panel performance?▾
Even partial shading can significantly reduce output. Traditional string inverters cause the whole string to underperform if one panel is shaded. Microinverters and DC optimizers mitigate this by allowing each panel to operate independently. If your roof has trees or chimneys that cause partial shading, request microinverters in your quotes.
How long does solar installation take?▾
The actual roof installation takes 1–3 days. However, the full timeline from signing a contract to system activation is typically 2–4 months, accounting for permit applications, utility interconnection approval, and inspection scheduling. Some fast-moving markets can complete the process in 6–8 weeks.
How do I size a solar system to my electricity bill?▾
Divide your monthly bill by your electricity rate to get monthly kWh, then multiply by 12 for annual kWh. Divide annual kWh by (peak sun hours × 365 × 0.80) to get approximate system size in kW. This calculator does all of that automatically — just enter your bill and state.
Does my roof need to be replaced before installing solar?▾
Solar installers recommend that your roof have at least 10–15 years of remaining life before installation. If your roof is more than 15 years old, consider replacing it first — removing and reinstalling solar panels costs $1,500–$3,000. A new roof paired with solar can sometimes be financed together. Most installers will assess your roof during the quoting process.
What is net metering and how does it affect my savings?▾
Net metering is a utility billing arrangement where your excess solar production flows back to the grid and you receive a credit on your bill — usually at the retail electricity rate. Most US states require investor-owned utilities to offer net metering, though credit rates vary. Our calculator assumes full retail-rate net metering credits.
