Solar Kits & DIY Solar
Size panels, MPPT controllers, batteries and inverters for RVs, sheds, cabins and off-grid systems.
Best Solar Kit for a Shed: Size Panels, Battery & Inverter Correctly
Size a shed solar kit from daily watt-hours, peak load, battery storage and realistic sun instead of buying by panel watts alone.
Best Solar Kit for an RV: 200W, 400W, 600W or 800W?
Choose RV solar wattage from daily battery use, roof space, LiFePO4 capacity and time between shore-power stops.
400W vs 800W Solar Kit: Which Array Size Is Worth It?
Compare 400W and 800W solar kits by daily harvest, battery recharge time, controller size, roof space and cost.
What Size Solar Panel for a 100Ah LiFePO4 Battery?
Estimate solar watts for a 100Ah lithium battery from voltage, state of charge, target recharge time and peak-sun-hours.
What Size Solar Panel for a 200Ah LiFePO4 Battery?
Size solar for a 200Ah lithium bank using battery voltage, usable energy, desired recharge window and controller capacity.
How Many Solar Panels Do I Need for a 5kWh Battery?
Estimate panel count for a 5kWh battery using recharge target, panel wattage, peak-sun-hours and system losses.
MPPT vs PWM Charge Controller: When the Upgrade Is Worth It
Compare MPPT and PWM controllers by array voltage flexibility, harvest, cold weather, cost and system size.
What Size MPPT Charge Controller Do I Need?
Estimate controller output amps from array watts and battery voltage, then check PV string voltage and current limits.
Best Solar Kit for an Off-Grid Cabin: Panels, Battery & Inverter Sizing
Size an off-grid cabin system from daily kWh, autonomy days, winter solar, inverter loads and generator backup.
Best Solar Kit for a Backyard Office or Studio
Size solar for a detached office with laptops, monitors, networking, lighting, heating/cooling constraints and battery storage.
Portable vs Rigid Solar Panels for RVs: Which Is Better?
Compare portable folding and permanently mounted rigid panels for harvest, setup time, shading, durability and travel use.
DIY Solar Kit vs Portable Power Station: Which System Should You Build?
Compare modular solar/battery systems with all-in-one power stations for cost, expandability, installation, portability and repairability.
