Answers for Massachusetts homeowners
Solar Myths & Frequently Asked Questions
Understand how solar, batteries, and your electrical system work together—and what to ask before planning your project.
Solar basics & common myths
Does solar work in Massachusetts winters and on cloudy days?
Yes. Solar panels use light, not heat. Clouds, shorter winter days, shade, and snow cover can reduce production. A useful proposal estimates seasonal and annual output for your actual roof and site instead of assuming every day performs the same.
Do solar panels store electricity?
No. Panels generate direct-current electricity, and an inverter converts it into alternating current for your home. A separate battery is needed to store energy for later use. See how solar powers a property.
Will solar eliminate my electric bill?
Not necessarily. Your bill depends on your usage, system production, utility charges, and the approved treatment of exported electricity. Financing payments may also be separate from the utility bill. We assess those assumptions before estimating savings.
Does my roof need to be replaced before solar?
It depends on the roof’s condition, remaining service life, structure, and available space. A roof nearing replacement should be addressed during planning so you can evaluate the cost and disruption of later removing and reinstalling panels.
Is the 30% federal homeowner solar credit still available for a new 2026 installation?
The IRS states that the Section 25D Residential Clean Energy Credit is unavailable for property placed in service after December 31, 2025. Business-owned and third-party-owned projects have separate rules. State and utility programs also require individual eligibility checks. Read our updated Massachusetts incentive guide.
Batteries, backup & your complete system
Will my solar panels keep the power on during an outage?
Most conventional grid-connected solar systems shut down when utility power fails. Backup requires compatible equipment and controls designed to isolate supported loads from the grid. Panels alone do not guarantee outage power.
Do I need a battery to install solar?
No. Grid-connected solar can supply household loads without a battery. Storage adds capabilities such as planned outage backup and shifting stored energy to another time. Whether it fits your project depends on your goals, utility arrangement, and budget.
Can BD add a battery to my existing solar system?
We can assess an existing system for a storage retrofit. The inverter, electrical service, panels, utility requirements, and chosen battery determine compatibility and the work required. Explore home battery storage.
Can solar, batteries, and a generator work together?
Yes, in supported configurations. Solar produces energy, batteries store it, and a compatible generator can add support during longer outages. Generator charging of batteries is equipment-specific; the controls and transfer arrangement must be designed for the selected products. Explore integrated backup options.
Do I need a smart panel or service upgrade for an EV charger?
Not every installation needs both—or either. We review existing capacity, the charger’s demand, other major loads, and supported load-management options. Smart controls can help manage loads but do not create additional electrical service capacity. Learn about smart panels or home EV charging.
Cost, installation & support
How much will my solar or energy system cost?
Cost depends on the site, equipment, system size, electrical upgrades, storage, and installation scope. We need project details before giving a meaningful proposal. Compare the installed price, financing costs, expected production, and verified incentives separately.
How long does a project take?
The schedule includes assessment, design, permits, any utility approvals, procurement, installation, inspections, and authorization to operate where required. Site conditions and utility review can affect timing. Your proposal should set out the expected sequence rather than promising a universal completion date.
How do equipment warranties and installation workmanship coverage differ?
Equipment warranties come from the manufacturer and apply to the specified products. Installation workmanship coverage addresses the installation work. Project-specific terms are provided with your proposal and contract. Contact BD about system questions and support.
Will my system need maintenance?
Monitoring and periodic review help identify changes in performance. Service needs depend on the equipment, installation, and manufacturer instructions. Discuss how issues are reported and who provides support. Do not climb onto a roof or handle electrical equipment to troubleshoot a system yourself.
What should I send BD to get started?
Send your project address, a recent electric bill, your goals, and information about existing solar or battery equipment. Panel photos or plans can help if safely available. Tell us about planned EV charging, heat pumps, backup loads, or other changes. Request an assessment.
