Solar energy isn’t perfect. While it’s revolutionized how we power our homes and businesses, five significant drawbacks continue to challenge homeowners considering the switch: high upfront costs that can exceed $20,000 even after incentives, dependence on weather and sunlight availability, space requirements that not every property can accommodate, energy storage limitations that require expensive battery systems, and disposal concerns for panels reaching end-of-life.
If you’re researching solar installations in 2026, you’ve likely encountered countless articles singing solar’s praises. That enthusiasm…

Solar panel degradation is the gradual loss of efficiency that occurs as photovoltaic cells age, typically measured as a percentage decline in power output per year. While it might sound concerning, modern solar panels degrade at remarkably slow rates, usually around 0.5% to 0.8% annually, meaning your system will still produce roughly 85% to 90% of its original output after 25 years of operation.
Understanding degradation matters because it directly affects your long-term return on investment and energy independence goals. When you’re making the decision to invest in solar technology, knowing that your panels won’t …
