Are AC modules easier to install than traditional panels?
AC modules are significantly easier to install than traditional solar panels because they have built-in microinverters, reducing installation time by 20-30%, requiring less wiring, eliminating separate inverter boxes, and improving safety during installation.
Are DC-coupled systems more complicated to install?
DC-coupled battery systems are actually simpler to install than AC-coupled ones, with fewer components and connections needed. They're more efficient too, losing less energy during conversion. The main complexity comes when retrofitting existing solar panels, which might need a new hybrid inverter.
Are EV tariffs different from normal electricity plans?
EV tariffs offer time-of-use pricing with overnight rates as low as 7p per kWh versus standard 25-30p rates. They require smart meters and compatible chargers, potentially saving £400-600 annually for typical drivers who charge at home overnight.
Are MCM panels more expensive than non-certified ones?
MCS-certified solar panels cost 10-20% more than non-certified alternatives, adding £600-1,200 to a typical £6,000 system. However, certified panels provide access to government incentives, insurance compliance, and better warranties, making them worthwhile for most UK homeowners.
Are NiCd batteries safe to use in a home setup?
NiCd batteries can be used safely at home with proper precautions, but they contain toxic cadmium and risk dangerous leaks. They're becoming obsolete, hard to replace, and require special disposal. Modern lithium-ion alternatives are safer and more practical.
Are VAT exemptions available across the whole country?
VAT exemptions on renewable energy systems are available nationwide across the UK at 0% rate until March 2027. This covers solar panels, heat pumps, wind turbines, and battery storage including professional installation costs for residential properties.
Are all new panels now made with half-cell technology?
No, not all new solar panels use half-cell technology, though it's becoming increasingly popular. Half-cell panels are mainly found in mid-range to premium models, while budget panels still use traditional full-cell design due to lower manufacturing costs.
Are all solar panels good for the environment?
Solar panels are good for the environment overall, cutting household carbon emissions by 1-2 tonnes annually. However, environmental impact varies based on manufacturing processes, durability, and recycling capabilities, with some panels being greener than others.
Are balcony solar panels safe in high winds?
Yes, balcony solar panels can be safe in high winds when properly installed with quality mounting systems engineered to European standards. These systems withstand winds up to 150 km/h, well above typical UK storm conditions, but require professional installation.
Are bioethanol fireplaces safe to use in UK homes?
Bioethanol fireplaces can be safe in UK homes if you use them properly, but they need careful handling since the fuel is highly flammable. They give off real flames without needing a chimney, though you'll need good ventilation and they're pricey to run long-term.
Are biomass boilers a good alternative to oil or gas heating in the UK?
Biomass boilers can slash heating bills by 30-50% and are much greener than oil or gas, but they need loads of storage space and cost £8,000-£15,000 upfront. They work brilliantly for rural homes without mains gas, though you'll need to handle deliveries and regular maintenance yourself.
Are built-in fireplace inserts safe to use in UK homes?
Yes, built-in fireplace inserts are safe for UK homes when professionally installed and maintained. They're much safer than open fireplaces, containing flames and properly venting gases. Professional installation by certified engineers is legally required for gas and wood-burning models.
Are bypass diodes useful in areas with lots of trees?
Bypass diodes are traffic controllers in solar panels that reroute electricity around shaded areas. They prevent one shaded cell from reducing entire panel output by 50%, maintaining efficiency in tree-heavy installations by only losing power from actually shaded cells.
Are ducted systems more efficient than ductless ones?
Ductless systems typically offer better efficiency than ducted systems because they deliver air directly to rooms without duct heat loss. Ducted systems can lose 20-30% of energy through poorly maintained ductwork, while ductless provides room-by-room control.
Are efficiency ratings regulated or standardised?
No, EV charger efficiency ratings aren't regulated in the UK. The Public Charge Point Regulations 2023 focus on reliability and pricing transparency, but don't require manufacturers to meet efficiency standards or display efficiency labels like household appliances.
Are electric wall-mounted heaters cheaper to run than gas patio heaters?
Electric wall heaters typically cost 60-70p per hour to run, while gas patio heaters cost £1.50-4 per hour - making electric roughly three times cheaper. Electric heaters work better for smaller patios and need proper installation, whilst gas suits larger spaces but requires regular bottle changes.
Are fireplace inserts more efficient than traditional open fires?
Fireplace inserts boost efficiency from 10-20% up to 70%, turning wasteful open fires into proper heating systems. They cost £800-3,000 plus installation but burn half the wood for better heat output, comply with UK emission rules, and typically pay for themselves within 3-5 years.
Are fittings included in the installation price?
Yes, reputable UK solar installers typically include all necessary mounting fittings and hardware in their quoted installation prices. However, some installers may exclude certain components, so always ask for a detailed breakdown before signing any contracts.
Are flexible panels as efficient as traditional ones?
No, flexible solar panels are not as efficient as traditional ones. Flexible panels achieve 10-18% efficiency while rigid panels reach 19-22%. However, flexible panels are lighter, portable, work on curved surfaces, and excel for boats, caravans, and temporary installations.
