Get answers to common questions about home solar services in East Derry, New Hampshire.
For an average East Derry home, a typical 8-10 kW solar panel system costs between $20,000 and $30,000 before incentives. Crucially, you can significantly reduce this with the 30% federal Investment Tax Credit (ITC), and New Hampshire's specific incentive: the $1,000 rebate for systems under 25 kW from the NH Public Utilities Commission. Additionally, you can participate in net metering with Eversource, earning bill credits for excess energy sent back to the grid.
Solar panels are very effective in cold, sunny weather, and they will still generate power in winter, albeit with shorter days. Snow will naturally slide off most properly angled panels, especially dark ones that absorb heat. It is generally not recommended to manually clear snow due to safety risks and potential damage to the panels; the system is designed to handle seasonal accumulation, and production spikes significantly in the spring and summer months.
Installation requires an electrical permit from the Town of East Derry Building Department and a building permit if the roof structure is being modified. Your chosen installer will typically manage this process. Importantly, you must also submit an interconnection application to Eversource, our local utility, to connect your system to the grid and enroll in their net metering program, which is a standardized process in New Hampshire.
Prioritize installers who are locally licensed, insured, and have extensive experience with New Hampshire's climate and Eversource's interconnection rules. Check for certifications like NABCEP and read reviews on local platforms. Ask for references from recent installations in nearby towns like Derry, Londonderry, or Windham to see their work firsthand and ensure they understand regional factors like optimal roof angles for our latitude and handling nor'easter weather.
While technically possible, going fully off-grid in East Derry is complex and costly due to our extended periods of cloudy weather and high winter energy needs, requiring a very large battery bank and generator backup. For most homeowners, a grid-tied system with a battery for backup (like a Tesla Powerwall or Generac PWRcell) is the practical choice. This provides power during Eversource outages while still allowing you to rely on the grid, maximizing savings through net metering.
