Solar systems in Dehradun require periodic maintenance to ensure they generate maximum power throughout their 25+ year lifespan. Uttarakhand's climate — whether dusty, humid, or variable — affects how frequently your panels need attention. A proactive maintenance approach protects your investment.
In Dehradun, solar panels should be cleaned every 3–6 weeks during dry season, and after dust storms or monsoon. Dirty panels can lose 10–25% output. Use soft cloth and clean water — never abrasive materials or pressure washers.
Schedule one comprehensive annual inspection: check inverter performance, wiring connections, mounting bolts, earthing system, and panel condition. This catches issues before they become expensive problems.
Annual Maintenance Contracts (AMC) in Dehradun cost ₹3,000–₹8,000 per year for a 3–5 kW system, typically including 2–4 cleaning visits and priority fault response. AMC is recommended for systems above 3 kW or owners who can't access the rooftop easily.

Use your inverter's monitoring app to track daily generation. If generation drops more than 15% without weather explanation, investigate promptly. Common causes: soiling, shading from new construction, inverter fault, or failed panel.
Keep all documentation — installation contract, commissioning certificate, inverter and panel warranties. For warranty claims, contact the original installer first, then the brand's service center directly if the installer is unresponsive.
Annual maintenance costs for a 3 kW system in Dehradun range from ₹2,000–₹6,000 depending on your cleaning frequency and whether you have an AMC. The biggest cost is professional cleaning — ₹300–₹600 per visit for a standard residential system.
Inverters are largely self-maintaining but should be checked annually: clean the cooling vents, check for error codes, and verify monitoring data. A full service by a technician every 2–3 years is recommended for inverters above 5 kW.
Key warning signs: generation consistently lower than expected by 10%+, inverter showing error codes or red lights, visible physical damage to panels (cracks, discoloration), loose mounting structure, or any burning smell near the inverter.
