Solar Hub
There’s plenty to weigh up before you put panels on a roof. Start with the question on your mind, then dig into the detail.
Your questions
Start with the roof, the shade and when you use electricity.
Usable space, orientation, shading, roof condition and electricity use shape the design. A roof survey confirms the practical layout.
A guide estimate cannot inspect access, cable routes or the electrical supply. The survey and agreed equipment determine the final proposal.
Find out what storage would do in your home before adding it to the system.
Not always. Look at surplus solar, evening demand and your tariff before choosing storage. More capacity is not automatically a better fit.
A battery does not automatically provide backup. The equipment, circuits and installation must be designed and confirmed for that function.
Think about where you park, when you charge and the electrical work needed.
Start with where you park, the cable route, the electrical load and when the car is usually at home. Confirm charger compatibility in the proposal.
Solar generation needs to coincide with charging. Available surplus, charger controls and the agreed system configuration affect what is possible.
Look at demand, site constraints and what a business proposal needs to cover.
No. Generation has to coincide with electricity use, or suitable storage is needed to use it later. Annual generation alone does not establish how much grid electricity you will replace, financial savings or permission to export.
A bill, the site location and operating hours are a useful start. Tell the consultant about roof access, deliveries and any shutdown constraints.
Know what you are comparing and what should be checked before work starts.
Ask for panel and inverter models, panel count, battery capacity if included, warranty terms and optional items. The layout needs to be checked for your property.
Confirm which commissioning documents, monitoring access, product information and support contacts you will receive.
