Installing solar panels used to feel like a futuristic luxury. Today, it’s one of the smartest home upgrades — for your wallet, your values, and the planet.
But with so many options (and sales pitches), it’s hard to know what’s really worth it.
At Zenda Guide, we’re here to help you cut through the jargon. Whether you’re comparing quotes, wondering how many solar panels you need, or asking if you can power your AC, this guide has the real answers — with affiliate links to vetted providers.
How Much Do Solar Panels Cost in 2025?
The average cost of installing residential solar panels in 2025 ranges from $12,000 to $25,000, depending on:
System size (kW)
Your energy use
Incentives in your region
Roof type and orientation
Installation method (DIY vs full-service)
System Size | Cost Range (USD) | Avg. Home Coverage |
1 kW | $1,000 – $2,500 | Small appliances only |
5 kW | $5,000 – $12,000 | 2–3 bedroom home |
10 kW | $10,000 – $20,000 | Large home w/ AC |
How Many Solar Panels Are Needed to Power a Home?
The average U.S. home needs 16–20 panels to fully cover energy use, depending on:
Average daily usage (kWh)
Sunlight exposure (location matters)
Efficiency of the panels (wattage per panel)
For example: A 6 kW system using 375W panels = about 16 panels.
Can a Solar Panel Run AC?
Yes — but only if your system is large enough and ideally paired with a battery or time-of-use metering.
Running a standard AC unit (1.5–2 kW/hour) would typically require 6–8 solar panels, depending on sun hours and efficiency.
Want to offset your summer energy bill? Consider adding extra capacity just for seasonal appliances.
What Will a 3000 Watt (3 kW) Solar Panel Run?
A 3 kW system (roughly 8–10 solar panels) can power:
A fridge
LED lights
Laptop + TV
Small kitchen appliances
Occasional AC use (partial)
It’s a solid entry point for small households, RVs, or part-time off-grid setups.
How Much Does a 1 kW Solar Panel Cost?
A 1 kW panel kit typically costs between $1,000 and $2,500, depending on:
Quality (mono vs polycrystalline)
Brand (Tesla, SunPower, etc.)
Whether it's a DIY kit or professionally installed
Great for:
Cabins, tiny homes, workshops, or minimalists
People testing solar before committing to full-scale install
