Practical reading
The questions behind a good decision.
Solar panels
Is my roof suitable for solar panels?
A practical roof-survey checklist covering usable space, orientation, obstructions and installation questions.
Solar panels
What should I expect from solar in winter?
Understand seasonal generation and why an annual solar total cannot establish winter self-sufficiency.
Battery storage
What size home battery do I need?
Compare usable energy and output power using a simple evening-demand example.
Battery storage
Can a home battery work without solar panels?
Understand the tariff-based case for a battery-only system and what a useful assessment should include.
Home backup
Whole-home or essential-circuit backup?
Compare backup coverage by supported circuits, simultaneous power and practical priorities.
Home backup
How long could a home battery last in a power cut?
Use available energy and average demand for an illustrative runtime calculation, then check the power limit.
EV charging
Can I charge my electric car from solar panels?
Plan around spare solar power, plug-in times and how an EV charger interacts with a home battery.
EV charging
V2H, V2G and backup: what is the difference?
Understand the separate roles of powering a home, exporting to the grid and operating during a power cut.
Energy tariffs
When does off-peak battery charging make sense?
Compare charging costs, losses and avoided imports before choosing a fixed battery schedule.
Energy tariffs
Should I store solar electricity or export it?
Compare export credit with the value of using stored solar later, including conversion losses.
Costs and savings
How should I assess solar and battery payback?
Understand simple payback, excluded costs and why incremental battery savings need a separate comparison.
Costs and savings
How to compare solar and battery quotations
Use a practical scope checklist to compare equipment, installation, assumptions and aftercare.

Clear about what we know.
These guides combine primary-source guidance with explicitly labelled examples. They explain current options and questions for an installer; they do not promise a particular product’s compatibility, a guaranteed saving or a future SolarIQ feature.
SolarIQ is developed and operated by GThink Ltd, the company behind electricalworks. Our calculation method explains the model, the information it uses and its limitations.
