TL;DR: Is solar panel efficiency worth it? It depends on one thing above all: how much roof space you have. Efficiency buys you more watts in the same area, so it pays off when space is tight and costs you money when it is not. On a large open roof, a standard panel plus one … Read more
TL;DR: Do solar panels increase property taxes? Sometimes, and it depends almost entirely on where you live. A solar array can raise your property’s assessed value, but many states exempt solar improvements from assessment. The answer is decided by your state law and your local assessor, so check both before you sign. Do Solar Panels … Read more
TL;DR: How long do solar batteries last? A modern lithium home battery typically lasts 10-15 years, or roughly 6,000-10,000 cycles, and most warranties guarantee 70% of original capacity for 10 years. Lead-acid banks last closer to 3-7 years, and heat is the single biggest thing that shortens any of them. How Long Do Solar Batteries … Read more
TL;DR: What size inverter do I need? A good starting point is 80-100% of your array size in kW, which means a 5kW array usually pairs with a 4-5kW inverter. The correct answer also depends on roof layout, whether you plan to add a battery, and how much clipping you are willing to trade for … Read more
TL;DR: How many solar panels to run an air conditioner depends on the unit, not the house. A modern 1.5-ton unit needs about 4-6 panels, a 3-ton unit 9-11, and a 4-ton unit 12-15 – and that only covers the hours the compressor is actually running while the sun is up. How Many Solar Panels … Read more
TL;DR: Grid-tied vs off-grid vs hybrid solar comes down to one question – does your house stay connected to the utility? Grid-tied is the cheapest and the default for most homes, off-grid gives full independence but costs two to three times more, and hybrid sits in the middle: grid power plus a battery, so the … Read more
TL;DR: Why is my electric bill still high with solar panels? Because solar offsets energy, not every line on the bill – and in most cases the cause is one of eight things: fixed charges the panels cannot touch, changed net metering rules, time-of-use rates, a system sized around last year’s usage, shading or soiling, … Read more
TL;DR: The main solar system components are the panels, the inverter, the racking that holds them down, the wiring and disconnect switches, the monitoring device and your utility meter. A battery is optional. The inverter is the part most likely to fail first and the part you will replace at least once in 25 years. … Read more
TL;DR: If your solar installer went out of business, the news is better than it sounds. Panel and inverter warranties belong to the manufacturers, not the installer, so they survive and stay claimable. What usually disappears is the workmanship warranty – the installer’s own promise covering roof penetrations, wiring and mounting. You can still get … Read more
TL;DR: What can a home battery run depends on three things: the size of the battery, which circuits are wired to it, and how much sun you get to recharge it. A 10kWh battery easily covers a fridge, lights, internet and a few outlets for a day – roughly the essentials for 8 to 12 … Read more
