Net Metering Explained

How net metering works globally, feed-in tariffs, virtual net metering, and community solar.

Grid
The number depends on your monthly consumption, panel wattage, and location sun hours. Typically: (Monthly kWh ÷ 30 ÷ sun hours ÷ 0.8) × 1000 ÷ panel watts. Our calculator automates this — enter your bill and location for an instant estimate.
Payback periods typically range from 5–10 years depending on your electricity rate, system cost, local incentives, and sun exposure. With government incentives like the US 30% ITC, payback can be as short as 4–6 years. After payback, solar is essentially free electricity for 15–20 more years.
Yes, solar panels still produce electricity on cloudy days — typically 10–25% of their rated output. Modern monocrystalline panels are better at diffuse light. Countries like Germany (average 3 sun hours/day) have thriving solar markets, proving solar works even in overcast climates.
Solar panels require minimal maintenance. Clean them 2–4 times per year to remove dust and bird droppings. Annual inspection of wiring and inverter is recommended. Inverters typically need replacement after 10–15 years ($1,000–$3,000). Most panels come with 25-year performance warranties.
On-grid systems are cheaper and simpler — you sell excess power back to the grid. Off-grid systems provide energy independence but require batteries, adding 40–60% to costs. For most homeowners, on-grid or hybrid systems offer the best balance. Off-grid is ideal for remote locations without grid access.
The inverter should be sized at 80–125% of your array's DC capacity. A common rule: for a 8 kWp solar array, use a 8–10 kW inverter. String inverters are most cost-effective for simple rooftops. Microinverters are better for shaded or complex rooftops. Hybrid inverters combine grid-tie with battery management.
kWp (Kilowatt Peak)
The rated maximum power output of a solar system under Standard Test Conditions (STC: 1000 W/m², 25°C).
kWh (Kilowatt Hour)
Unit of energy. 1 kWh = 1 kW of power used for 1 hour. Your electricity bill is measured in kWh.
Peak Sun Hours (PSH)
The number of hours per day when solar irradiance averages 1000 W/m². Not the same as daylight hours.
Net Metering
A billing arrangement where solar users receive credit for excess electricity exported to the grid, reducing their net bill.
MPPT
Maximum Power Point Tracking. Electronic system in inverters that continuously optimizes the power harvest from solar panels.
DoD (Depth of Discharge)
The percentage of a battery's capacity that can be used. LFP batteries: 80–100% DoD. Lead-acid: 50% DoD.
String Inverter
A central inverter connected to a string (series) of solar panels. Most common and cost-effective for unshaded rooftops.
Microinverter
Individual inverter attached to each panel. Better for shaded or complex roofs. Higher cost but panel-level monitoring.
PV (Photovoltaic)
Technology that converts sunlight directly into electricity using semiconductor materials. What solar panels are made of.
STC (Standard Test Conditions)
Reference conditions used to rate solar panels: 1000 W/m² irradiance, 25°C cell temperature, AM1.5 spectrum.
ROI (Return on Investment)
Total net savings over the system lifetime divided by the net investment cost, expressed as a percentage.
LFP (Lithium Iron Phosphate)
The safest and most durable lithium battery chemistry. Used in Tesla Powerwall, BYD, and Pylontech. 4000+ cycles.
