Spring and Fall are usually the best times to install solar panels since there’s usually less demand for new installations. Contractors often have better availability and rates during non-peak periods. The mild weather conditions of these seasons also allow for more comfortable contractor work and minimal weather delays.
Solar panels can save money long-term. A correctly sized system can eliminate most or all of your electricity bill. If you save $100 per month, for example, your savings can add up to over $50,000 over 30 years. Your actual savings depend on your system’s efficiency, local electricity rates, and other factors.
The average solar system recovers its post-tax credit cost in between 6 and 10 years. Purchasing your system upfront without financing, tax credits, net metering, panel efficiency, and other factors can shorten the time it takes to recoup installation costs. For example, the average annual energy bill in 2023 was $1,650. If your system costs $15,000 after tax credits and covers your entire energy demand, your system earns your costs back in about nine years.
Solar panels have an average lifespan of 25 to 30 years, largely depending on the type—mono and poly solar panels last from 25 to 40 years, while thin-film panels 10 to 20 years. Regular maintenance, proper installation, and prompt repairs help extend the longevity of your system.
A properly sized system can meet the full energy demand of your home. Switching entirely to solar power requires careful planning and depends on energy consumption, sunlight availability, battery storage, and budget.
