What should a solar quote include?
A good solar quote should make it easy to understand what you are buying, what it costs, what performance is predicted and who is responsible for each part of the installation.
What to check
- Total price and payment schedule
- Panel quantity, make and model
- Inverter and battery model
- System capacity and predicted generation
- Scaffolding and installation work
- Warranties and guarantees
- Installer certification
- Savings assumptions
Equipment details
The quotation should name the products clearly enough that you know what is being proposed. Generic phrases such as “premium 450W panels” make comparison and warranty checking harder.
What installation work is included?
Look for scaffolding, electrical work, monitoring, grid-connection responsibilities, final setup and any exclusions. A cheaper-looking quote can become more expensive if essential work sits outside the headline price.
Savings assumptions
A projected payback period only makes sense if the assumptions about electricity use, generation, import costs and export income are clear.

Frequently asked questions
Should scaffolding be shown on a solar quote?
If scaffolding is needed, it should be clear whether it is included or excluded from the total price.
Should the exact panel model be named?
Ideally yes. Exact product identification makes it much easier to check the specification and warranty.
We keep a clear line between what a quote says, what can be calculated and what still needs checking. We do not accept payment from installers to change the outcome of a quote check.
