Going solar in San Diego? Your solar installer handles the panels — we handle the electrical foundation. Panel upgrades, sub-panels, utility company interconnection, and all permits, done right so your solar system performs at its best.
Solar panels and battery systems generate and store significant power. Your electrical panel is the hub that connects it all — solar inverter, battery system, your home's circuits, and the your utility company grid. An undersized or outdated panel is the most common reason solar projects get delayed in San Diego County.
Many San Diego homes still have 100-amp panels — which are insufficient to safely support a modern solar-plus-battery system. We assess your current panel, upgrade it if needed (including full utility company service order coordination), and ensure everything is ready for your solar installer.
About Our Panel Upgrades →Most solar + battery systems require at least 200A service. We upgrade your panel and handle the utility company service order.
For battery backup systems (Tesla Powerwall, Enphase, etc.), we install a dedicated sub-panel for critical loads.
Solar systems must be approved by the utility company before they can connect to the grid. We handle all utility coordination.
Upgrade your main panel to 200-amp (or 400-amp for larger systems), with full utility company service order coordination included.
Dedicated circuits and sub-panel installation for Tesla Powerwall, Enphase IQ Battery, LG RESU, Franklin WH, and all major battery brands.
Proper dedicated circuits for string inverters, microinverters, and hybrid inverter systems meeting NEC and California code requirements.
All city electrical permits pulled and final inspections passed — your solar project can't be commissioned without these.
We handle the electrical side of the utility company's interconnection process, ensuring your solar system gets permission to operate on schedule.
Adding an EV charger to your solar project? We can wire both simultaneously, maximizing efficiency and minimizing the number of inspection visits.
Often yes. Solar inverters and battery systems require adequate panel capacity. Many San Diego homes with 100-amp panels need an upgrade to 200-amp service before solar can be safely installed. Kaspar Electric handles the full panel upgrade and utility company coordination, so your solar installer can proceed without delays.
Typical solar electrical scope includes: panel capacity assessment, service upgrade if needed, dedicated inverter circuits, sub-panel for battery backup (if applicable), utility company interconnection coordination, and all city permits. Kaspar Electric handles every part of this.
If a panel upgrade is required, the utility company service order process adds 4–8 weeks before the electrical upgrade can begin. The actual electrical installation is typically completed in one day. We recommend contacting us as early as possible in your solar planning process to avoid delays.
Absolutely — and it's one of the smartest combinations available. When you charge your EV from solar during the day, you're essentially driving on free, clean energy. We can wire your EV charger as part of the same project, often saving time and reducing the number of city inspection visits required.
Yes. We regularly coordinate with solar installation companies throughout San Diego County. If your solar company needs a licensed C10 electrician to handle the electrical scope of work, we can work directly with them to ensure the project stays on schedule.
