Read the electric bill
Find monthly usage, annual usage, supply charges, delivery charges, and whether the utility has time-of-use rates.
- Write down annual kWh use.
- Note your highest-use months.
- Keep a copy for quote comparisons.

Solar and Clean Power
Once a home is using less energy, cleaner electricity becomes easier to understand. This section helps people compare solar, community solar, green-power plans, batteries, incentives, and installer quotes without getting overwhelmed.
On this page
Use this chapter to compare solar, community solar, batteries, and cleaner-power options.
Solar readiness
Start with the basic questions.
Solar planning is not just about panels. It is about the electric bill, the roof, shade, utility rules, financing, warranties, and whether the system fits how the home actually uses power.
Check roof and shade
Roof age, direction, slope, tree shade, and nearby buildings all affect solar output and installation cost.
- Do not install on a roof that needs replacement soon.
- Notice shade during different parts of the day.
- Ask installers for production estimates, not just panel counts.
Compare quotes
A good quote should explain system size, estimated production, total price, equipment, warranties, timeline, and assumptions.
- Get more than one quote.
- Compare total cost, not only monthly payment.
- Ask what happens if production is lower than projected.
Look at non-roof options
Renters, shaded homes, apartments, and unsuitable roofs may still have options through community solar or cleaner utility plans.
- Check community solar availability.
- Review green-power plans carefully.
- Confirm cancellation terms and fees.
Options
Choose the clean-power path that fits the home.
The best option depends on ownership, roof condition, local policy, budget, resilience needs, and how long someone expects to stay in the home.
| Option | Best for | What to check | Watch out for |
|---|---|---|---|
| Rooftop solar | Owners with a suitable roof and long-term plans. | Roof age, shade, utility rules, incentives, permits, warranties. | High-pressure sales, unclear financing, unrealistic savings claims. |
| Community solar | Renters, shaded homes, condos, or homes not ready for panels. | Availability, subscription rules, savings estimate, cancellation policy. | Confusing contract terms or savings that depend on uncertain credits. |
| Battery backup | Homes needing outage protection or better use of solar power. | Backup loads, battery size, warranty, safety, installation cost. | Buying a battery before knowing what problem it needs to solve. |
| Green-power plan | People who cannot change equipment yet but want a cleaner supply option. | Source quality, contract terms, price, renewable energy certificates. | Marketing claims that do not clearly explain what is being purchased. |
Quote questions
Ask these before signing.
Clear answers are part of a good solar process. If the answers are vague, slow down.
System and production
What size is the system? How much electricity is it expected to produce each year? What assumptions were used?
Cost and financing
What is the total price before incentives? What happens if the home is sold? Are there dealer fees or escalators?
Equipment and warranty
What panels, inverters, racking, and monitoring are included? Who handles service if something fails?
Permits and timeline
Who handles permits, inspection, utility interconnection, and activation? How long does each step normally take?
