Solar installation is the core of what we do on the solar side. Layout, mounting, wiring, inverters, permits. All of it planned around the roof first, not treated as an afterthought.
San Diego sun is great for production, but roof condition, pitch, and exposure matter more than most people realize. We look at the whole setup before anything goes on the roof.
Panels don’t fail often, but connections, wiring, and mounts can. Solar panel repair usually comes up after storms, roof work, or older installs that weren’t done clean. We track down the actual issue, not just what’s throwing an error. Roof and solar problems are often connected.
Older panels don’t produce like newer ones. Damage can also make replacement necessary. Solar panel replacement focuses on upgrading or swapping panels without creating roof issues. Matching new equipment to existing systems takes planning, especially on tile and older roofs.
Roof work sometimes means panels have to come off. Solar removal and reinstallation needs to be done carefully so nothing is damaged going up or coming back down. This comes up a lot with roof replacement and major repairs. One crew handling both sides avoids problems.
Battery storage gives homeowners control over power use helping reduce peak hour pricing. Solar battery storage installation is often paired with solar installs or added later. Proper placement, wiring, and compatibility matter, especially with heat and garage conditions here. In 2026 most people ask us for the tesla powerwalls for their battery back ups.
Many solar customers look into solar when they have a EV like a tesla. Charging at home is expensive without the help of solar. EV charger installation ties into existing electrical systems and solar setups. Panel capacity and load need to be checked first. It’s not always plug-and-play.
Residential solar solutions cover homes of all shapes and ages. Older houses, newer builds, tile roofs, flat sections. Each one installs differently Solar works best when it’s matched to how the home actually uses power.
Larger buildings need different planning and thats where we come in. Commercial solar panel systems focus on usage patterns, roof space, and long-term performance. Warehouses, offices, and retail buildings all bring different challenges that we specialize in.
