Shading analysis is a core part of professional solar design, modeling how trees, chimneys, and neighboring structures will affect sunlight on your roof throughout the entire year — not just at the moment of the site visit. Modern shading analysis uses specialized software to predict sun position and shadow patterns across all seasons, informing both Read more »
Beyond rooftop systems, small-scale solar power runs an expanding range of everyday devices and wearables, from garden lights to smartwatches. Solar-powered appliances and wearables trade small solar cells for reduced or eliminated battery dependence in low-power devices. Common Solar-Powered Devices Device Category Examples Wearables Solar watches (Citizen Eco-Drive, G-SHOCK, Seiko Astron) Outdoor devices Garden lights, Read more »
Solar water heaters are one of the most cost-effective solar energy investments for most US homes — with payback periods of 5–10 years, they offset 50–80% of domestic hot water costs using free solar energy. Unlike photovoltaic panels that convert sunlight into electricity, solar water heaters capture solar heat directly using collectors on the roof Read more »
Many homeowners in HOA communities worry their association can block solar installation entirely — but most states now have solar access laws limiting what HOAs can restrict. 44+ states protect homeowners’ right to install solar, though HOAs can still regulate placement, appearance, and installer requirements. What HOAs Can and Can’t Restrict HOA Authority Typically Allowed? Read more »
Heating and cooling account for a large share of home energy use, and solar can offset this load either indirectly (powering electric heat pumps) or directly (solar thermal systems). Solar PV paired with a heat pump is the most practical solar-powered HVAC solution for most homes today. Solar Approaches to Heating and Cooling Approach How Read more »
Solar cooling systems use solar energy to provide air conditioning or refrigeration — reducing grid electricity consumption for what is often a building’s largest summer energy load. As air conditioning demand grows globally, solar cooling represents a natural alignment: cooling demand peaks when solar irradiance is highest, making solar power and cooling a complementary pairing.

Solar Air Heating Systems: 2026 Complete Guide Solar Air Heating Systems: How They Work and When to Use Them Solar air heating systems capture sunlight and convert it to warmth, which is then distributed through your home via air ducts to heat living spaces. Unlike solar photovoltaic (PV) systems that generate electricity, solar air heating Read more »
Selling a home with a leased solar system requires transferring the lease agreement to the new buyer, a process that can complicate — but doesn’t have to derail — a home sale. Most solar leases transfer to the new homeowner through a formal application process requiring lender/leasing company approval. Solar Lease Transfer Process Step What Read more »
Adding battery storage to a solar system unlocks capabilities that grid-tied solar alone can’t provide. The core benefits are time-of-use rate optimization, backup power during outages, rate protection against future utility increases, and eligibility for virtual power plant programs in some areas. Time-of-Use (TOU) Rate Optimization Under NEM 3.0 and similar TOU-based rate structures, exporting Read more »
Choosing a solar battery system involves balancing capacity, chemistry, brand reputation, and your specific backup goals — there’s no one-size-fits-all answer. Define your backup priorities first (essential loads vs. whole-home), then size capacity and choose LFP chemistry from a reputable brand. Solar Battery Selection Framework Decision Key Considerations Backup goals Essential loads only vs. whole-home Read more »
