How long a solar battery powers a house depends on the battery’s usable capacity and your household’s power draw during the outage or overnight period. A single 10-13 kWh battery (like a Tesla Powerwall) typically covers 8-24 hours of essential loads, while whole-home backup requires larger capacity. Solar Battery Runtime Estimates Battery Size Essential Loads Read more »
Solar doesn’t necessarily eliminate your electric bill, but it typically cuts it dramatically — the exact amount depends on system size, local rates, and net metering policy. Most solar homeowners see their monthly bill drop to $10-$30 (often just a grid connection fee), down from $150-$200+ without solar. Average Monthly Electric Bill: Solar vs. No Read more »
Pressure washing seems like an efficient way to clean solar panels, but the high force can crack glass, damage seals, and void manufacturer warranties. Manufacturers universally recommend gentle hand-washing over pressure washing, which risks costly damage to panels and their protective seals. Pressure Washing Risks to Solar Panels Risk Consequence Glass cracking/microcracks Reduced output, potential Read more »
Can You Power a Hot Tub with Solar Panels Can You Power a Hot Tub with Solar Panels? A Complete Guide for 2026 Yes, you can power a hot tub with solar panels—but it requires careful planning, adequate system sizing, and often battery storage to run jets and heaters 24/7. Solar hot tubs are increasingly Read more »
Solar power is more reliable than most people expect — and in specific ways less reliable than they’d prefer. Solar panels themselves are extremely reliable hardware: no moving parts, 25-year warranties, and failure rates under 0.1% annually. The reliability questions that matter to homeowners are about operational reliability — will my system produce power when Read more »
How long a 12V battery powers an inverter-connected load depends on battery capacity, the connected load’s wattage, and inverter efficiency losses. A 100Ah 12V battery typically runs a 100W load for roughly 8-10 hours through an inverter, accounting for conversion losses. 12V Battery Runtime Estimates Battery Capacity 100W Load 300W Load 50Ah ~4-5 hours ~1.3-1.7 Read more »
When a solar panel isn’t charging a battery, the cause is almost always one of five things: the panel isn’t producing enough voltage to overcome the battery’s current voltage, there’s a fault in the charge controller, the wiring has a connection issue, the battery is sulfated or at end of life, or the system is Read more »
Transparent solar panels promise to turn windows and glass surfaces into power generators, but current technology involves real efficiency tradeoffs compared to opaque panels. Transparent solar technology (luminescent solar concentrators and thin-film) currently achieves lower efficiency than standard panels, limiting practical applications. Transparent Solar Technology Types Technology Transparency Typical Efficiency Luminescent Solar Concentrators (LSC) High Read more »
Solar buyback refers to the process by which your utility company compensates you for excess solar electricity your system sends back to the grid. When your solar panels produce more electricity than your home uses at that moment, the surplus flows to the grid — and your utility credits or pays you for it. The Read more »
Lithium (LiFePO4) batteries have become the default choice for most new solar installations, but they aren’t automatically the right fit for every situation. For most home solar-plus-storage systems, lithium iron phosphate (LFP) batteries are the best overall choice due to their lifespan, safety, and total cost of ownership — but lead-acid still wins in a Read more »
