This home solar FAQ gives short, sourced answers to the 40 questions we see most, each linking to a deeper guide in our Home Solar series. Are solar panels worth it? That’s the question behind most solar threads on Reddit and homeowner forums. The honest answer depends on your electric rates, sun, roof and how […]
The Tesla Powerwall 3 warranty is a good starting point for comparing home batteries, because every major brand words its warranty a little differently. Most cover around 10 years, but the details that matter are capacity retention (how much storage is guaranteed at the end) and any energy throughput cap that can end coverage early. […]
Is a solar panels on roof fire hazard worth worrying about? Rooftop PV fires are uncommon, and most trace back to installation faults rather than the panels themselves. Modern codes add protections for both homeowners and firefighters. Knowing what causes problems, and what good installs do differently, puts the risk in perspective. Electrical work can […]
Solar panels for 1000 kWh per month usually come to somewhere around 20 to 27 panels, with typical sun and 400W panels. That’s 12,000 kWh a year, a bit above the US average. Batteries are a separate question, and depend on whether you want backup, bill savings or both. Solar Panels for 1000 kWh per […]
An off grid solar system for home use has to do everything the utility does: make power, store it and deliver it on the worst winter week. That makes it far bigger and more expensive per kWh than a grid-tied system of the same size. Sizing starts with your loads, not your roof. Electrical work […]
A home battery backup for power outage use, paired with the right inverter and switching equipment, is what keeps lights on when the grid goes down. A standard grid-tied inverter must shut off in an outage to protect utility workers, so many solar owners are surprised the first time their panels stop powering the house. […]
How many solar panels to charge a Tesla or other EV? For a typical driver doing about 12,000 miles a year, the answer is usually around 6 to 10 panels of 400W added to your home system. The exact number depends on how far you drive, how efficient the car is and how much sun […]
Solar panels for a 2,000 sq ft house are sized by how many kWh you use per year and how much sun you get; square footage is only a rough guide. Here’s a worked example with typical numbers, so you can redo it with your own bill. Step 1: Estimate Usage for a 2,000 sq […]
The kWh meaning in your electricity bill is simple: a kilowatt-hour (kWh) is 1,000 watts used for one hour, and understanding it is the first step in going solar. Your utility charges you for the kWh you use, plus some fixed charges. Solar can only offset the parts tied to kWh, so knowing how your […]
Knowing how to choose a solar installer matters more than picking a panel brand. The installer designs the system, pulls the permits, puts holes in your roof and stands behind the work for years. The FTC warns homeowners about high-pressure sales and misleading savings claims, so go in with a checklist and get at least […]
