What is the payback period for solar panels in Hendy?
With a cost of £6,600-£8,500 (0% VAT included) and savings of £605+ per year based on Hendy's solar yield of 850 kWh/kWp at current electricity rates of around 25p/kWh, plus Smart Export Guarantee income of around 13-15p/kWh for surplus electricity, a typical solar system in Hendy pays for itself in 11-13 years. Carmarthenshire ranks #55 of 102 UK counties, and solar still pays off here thanks to longer summer daylight hours and cooler temperatures that help panels run more efficiently. After payback, you benefit from 12-19 years of near-free electricity as panels last 25-30 years. Adding a battery extends self-consumption and can reduce payback further if you use most electricity in the evenings. Total lifetime savings typically reach £15,000-£18,000 depending on your usage pattern.
How do I get the best deal on solar panels in Hendy?
Get at least 3 quotes from MCS-certified installers to compare pricing, equipment brands, and warranty terms. Check each company is registered with MCS at mcscertified.com, this certification is required for Smart Export Guarantee eligibility. Look for 25-year panel performance warranties and 10-15-year inverter warranties as a minimum. Ensure your installer includes the DNO notification (G98/G99 application) and handles all paperwork. Remember that 0% VAT applies automatically to residential installations, so you should not be charged any VAT on the total cost.
Do I need planning permission for solar panels?
Most residential solar installations in the UK are classed as permitted development and do not require planning permission, provided panels do not project more than 200mm from the roof surface. Listed buildings, conservation areas, Areas of Outstanding Natural Beauty (AONBs), and World Heritage Sites may have additional requirements from your local planning authority. Ground-mounted systems are also permitted development if they do not exceed 9m² in area. Your MCS-certified installer can advise on any local restrictions that apply to your property.
What happens to my solar panels if I move house in Hendy?
Solar panels stay with the property as a permanent fixture and transfer to the new owner upon sale. They add value to your home, up to 4% according to UK property research, and improve the EPC rating, making the property more attractive to energy-conscious buyers. Your installer can transfer monitoring app accounts and warranty documentation to the new owner. The Smart Export Guarantee registration also transfers with the property. With a 25-30 year lifespan, the next owner inherits many years of remaining electricity savings.
Can I add a battery to my solar system?
Yes. A home battery (typically 5-10 kWh capacity) stores excess solar electricity generated during the day for evening and overnight use. This increases your self-consumption from around 40% to 60-80%, significantly reducing your reliance on grid electricity. Batteries currently cost £3,000-£6,500 for 5-10 kWh and also benefit from 0% VAT on residential installations. Most batteries are warranted for 10-12 years and can be retrofitted to an existing solar system. Popular options include the Tesla Powerwall 3, Sigenergy, and FoxESS units.
Do I need a smart meter for solar panels?
A smart meter is required to sell surplus electricity back to the grid under the Smart Export Guarantee (SEG) and earn around 13-15p/kWh for your exports. Your energy supplier will install a smart meter for free if you do not already have one, contact them before or shortly after your solar installation. You do not strictly need a smart meter for the solar panels themselves to work, but without one you cannot receive SEG payments. Your MCS-certified installer submits the G98/G99 application to your Distribution Network Operator after installation to register your system for grid export.
