Frequently Asked Questions

Solar is renewable, reliable, and clean energy that reduces reliance on fossil fuels. With a solar system, you benefit from predictable energy rates for 35 years and take control of your energy future.

Suitability depends on your location, roof angle, shade, and home age. Our solar advisors conduct a custom analysis to determine if your home qualifies and assess your energy needs.

The number of panels depends on your power requirements (based on utility bills), climate, and roof characteristics. We customize every system to maximize energy production for your specific home.

Your past usage allows us to customize an appropriately-sized system. A full year of data reveals seasonal variations needed to match your home's actual consumption patterns.

Common incentives include tax credits, net metering, and utility rebates. Federal and cantonal solar incentives can significantly reduce the cost of your system.

Studies show that homes with solar sell for approximately 4% more than homes without. Installing a solar system increases your home's appeal and value for potential buyers.

A typical installation includes crew arrival and preparation, system design review, panel and wiring installation, cleanup, and a final walk-through explaining system operation and activation procedures.

Installation requires drilling holes to anchor racking equipment. All roof penetrations are waterproofed and guaranteed by our workmanship warranty. Solar panels actually protect underlying roof sections from weathering.

Standard components include solar panels (converting sunlight to DC electricity), an inverter (converting DC to AC), a monitoring meter, the main electrical panel, and a utility meter.

Installation typically completes in one day. Pre-installation preparation takes several weeks, including site survey, design finalization, permit application, and obtaining necessary approvals.

Your home becomes powered by roof-mounted solar. You can monitor production through our online portal. Monthly bills arrive 30 days after system activation for monthly-payment customers.

Permission to Operate (PTO) grants permission to connect your system to the utility grid — it's required before activation. We submit interconnection applications following inspection completion, which typically takes 2–6 weeks.

Solar panels convert sunlight to DC electricity. Inverters transform it to AC electricity powering your home. Excess energy flows to the grid, while the monitoring meter tracks production and the utility meter tracks grid exchanges.

Solar systems produce electricity in all weather conditions. Cloudy-day production typically reaches 10–25% of capacity. System designs account for regional sunlight variations to ensure appropriate sizing.

Yes, systems produce year-round, though output fluctuates seasonally. Summer production peaks with longer days, while winter production declines due to shorter days and variable weather. Designs account for seasonal variation.

Panels require sunlight and remain dormant at night. Net metering credits enable using nighttime grid power, and battery storage enables consuming daytime-produced electricity after sunset.

Solar systems automatically deactivate during outages to protect utility workers on power lines. Systems restart automatically when utility power restores. Battery-equipped systems continue providing backup power during outages.

Panels continue producing well past 35 years, declining approximately 0.5% annually. After 35 years, systems operate at roughly 82% of their original capacity, providing continued clean renewable energy.

Leasing requires minimal upfront costs with included maintenance. Purchasing offers direct access to tax credits and incentives but requires maintenance responsibility outside warranty coverage. Both options have unique advantages depending on your situation.

Solar leases involve a fixed monthly payment for system use. Power Purchase Agreements (PPAs) charge per kilowatt-hour for generated electricity. Both require minimal upfront costs and include maintenance.

Systems typically cost between CHF 15,000–29,000 for 4kW–8kW capacities depending on your canton and home. Flexible financing options enable going solar with little to no money down.

Solar replaces unpredictable utility rate increases with locked-in, predictable rates. The greater the utility rate increases over time, the larger your solar savings become.

You remain grid-connected, purchasing supplementary power during insufficient production (cloudy days, winter, nighttime). Standard connection fees apply even when solar provides all your electricity.

Federal and cantonal tax incentives can significantly reduce the cost of your solar system. Contact our solar advisors for details on the specific incentives available in your area.

Trim nearby trees for maximum sun exposure. Spray dusty panels with water — rainy days typically provide sufficient cleaning. Avoid cleaning snow as it naturally slides off.

Yes, a dedicated monitoring team watches continuously. Meters send production data multiple times daily. Daily evaluation confirms expected performance, and any problems trigger investigation and repair.

We handle all repairs and replacements throughout your agreement. Report issues through our support portal for immediate agent assistance.

Yes, equipment is backed by robust warranties including 24/7 monitoring and maintenance. Any breakdowns receive free repair service for the duration of your agreement.

Contact our customer care for removal and reinstallation quotes. Our local teams temporarily remove panels during roof replacement. We recommend providing 45 days advance notice when possible.

Shade reduces panel efficiency. Our design accounts for existing shade, however future tree growth may decrease production. Trimming trees maximizes your panels' sun exposure.

Batteries can backup your kitchen (including refrigerator), bedroom and bathroom lights, garage door opener, and WiFi for approximately 8–12 hours. Solar panels recharge batteries at sunrise.

During outages, batteries power backed-up circuits within seconds, providing 8–12 hours of backup energy depending on usage. Solar panels recharge batteries daily, enabling multi-day outage support.

Systems remain grid-connected when utility power is available. During outages, the battery 'islands' from the grid, powering selected areas of your home. Grid reconnection occurs automatically when utility power restores.

Battery sizing depends on your unique energy needs, consumption habits, and which appliances you want backed up. A professional assessment determines the appropriately-sized system for your specific requirements.

Batteries are typically wall-mounted inside garages or on exterior home walls. Installation requires approximately 6.5 feet of height by 10 feet of width clearance.

Installers handle all configuration with optimized settings. Batteries last 10–15 years with typical 10-year manufacturer warranties. Our maintenance plan includes 35 years of professional monitoring.

Solar systems offset their manufacturing emissions within 10 months. Over their lifetime, they prevent carbon emissions equivalent to driving nearly 500,000 miles.

Solar adoption provides clean electricity with zero emissions. Home-generated power reduces grid strain during peak demand, benefiting your entire community's safety and infrastructure.

Net metering tracks excess solar power you send into the grid. Your utility credits these exports against future grid purchases, ensuring your solar power never goes to waste.

Utilities provide credits for excess solar-produced power fed into the grid. Energy used immediately from solar never enters billing. Battery-stored energy similarly avoids grid entry and billing impact.
