Frequently Asked Questions

Solar cells absorb sunlight and release electrons, creating direct current. An inverter converts that into alternating current for your appliances, while surplus energy can charge batteries or feed the grid.

Divide daily energy use by local peak sun hours, panel wattage and about 0.8 for losses. Ten kWh daily at five sun hours with 400 W panels needs roughly seven.

Compare efficiency, power rating, temperature coefficient, degradation rate, certification and warranty. Limited roof space favours monocrystalline; spacious sites may prioritise cost per watt.

Cost depends on system size, panel and inverter quality, mounting, batteries, labour and local conditions. A site-specific quotation, based on your consumption and roof or land, is the only reliable figure.

Quality panels typically last twenty-five to thirty years or more, with performance warranties guaranteeing a minimum output near year twenty-five. Inverters usually need replacement after ten to fifteen years.

Rinse with clean water and a soft brush when dusty, preferably in the cool morning. Avoid abrasives and pressure washers, and inspect connectors, shading and mounting periodically.

Price depends on usable capacity, chemistry, brand, inverter compatibility and installation. Compare cost per usable kilowatt-hour over the warranted cycle life, not only the upfront price.

Match usable capacity to your backup loads, confirm voltage and inverter compatibility, and compare depth of discharge, cycle life, warranty and safety certification. Lithium iron phosphate is popular.

Runtime equals usable battery energy divided by the load. A 10 kWh usable battery supplying 1 kW lasts about nine to ten hours after conversion losses.

Match continuous and surge power to your loads, check the panel voltage against the MPPT window, and confirm battery voltage, grid compatibility and monitoring. Hybrid models simplify storage.

Grid-tied systems work with the grid and stop in outages. Hybrid systems add batteries for backup. Off-grid systems operate independently using batteries, often with a generator.

Lithium iron phosphate batteries commonly deliver three thousand to six thousand cycles, roughly ten to fifteen years. Deep-cycle lead-acid batteries often last three to seven years.

Usually yes. AC-coupled battery inverters work with most existing grid-tied systems, while DC-coupled options need compatible hybrid inverters. Check warranties, switchboard capacity and local rules first.

Survey and design the system, obtain approvals, install mounting, wire panels, inverter, batteries and protection, then test and commission. Licensed professionals should handle electrical connections.

Divide net system cost by annual savings for payback. Include degradation, tariff changes, maintenance, battery replacement and incentives for a fuller return picture.

Common causes are shading, dust, tripped breakers, loose connectors, inverter faults, wrong tilt, seasonal change or grid voltage limits. Compare monitoring data with expected yield.

Keep ventilation clear, check terminals and error logs, update firmware and monitor battery temperature and state of charge. Schedule professional inspections annually.

Use the inverter portal, add an energy meter or current clamps, and review daily yield and consumption. Alerts help detect faults quickly.

Install rooftop solar to offset daytime consumption, add storage to cut peak demand charges, improve efficiency, and analyse tariffs using interval meter data.

Analyse interval load data, then define the power in kW for peaks and energy in kWh for duration. Include efficiency, depth of discharge, degradation and safety requirements.

Check experience, equipment quality, certifications, warranties, financial stability, references and maintenance capability. Compare bids on lifetime value and compliance, not price alone.

Divide net capital cost by annual savings, adjusted for degradation, tariff escalation, operating costs, incentives and tax treatment. Present net present value alongside payback.

Gather load data, assess roof structure and shading, define goals, design the system, secure approvals, tender equipment, schedule installation around operations and plan maintenance.

Panels still produce reduced power under cloud, but not at night. Batteries or the grid supply evening demand, and production varies by season.

Total essential loads, add motor starting surges and allow about twenty percent headroom. A generator loaded to roughly half to three quarters of rating runs most efficiently.
