Insights
Useful guidance for solar, storage, EV and grid decisions.
Explore guidance on solar PV, batteries, EV charging, grid connections and project economics, including dated references for rules and guidance that can change.
START WITH THE DECISION YOU ARE TRYING TO MAKE
Technical answers for real solar, storage and grid decisions.
Use the library to understand the decision points behind solar, storage, grid connection, export, project economics and current tax treatment.
01Grid + connection
Use the G98/G99/G100 guidance to understand why connection strategy belongs early in the design.
02Performance + storage
Generation estimates and battery kW versus kWh explain why capacity figures alone are not enough to compare systems.
03Economics + current rules
Commercial ROI, SEG and VAT guidance help separate engineering assumptions from tariff, tax and policy conditions that can change.
HOW WE WRITE
Understand the design choices behind the terminology.
The library is organised around recurring project questions so technical guidance connects directly to the decisions customers need to make.
STARTER GUIDES
Start with the questions that affect real projects.
GRID / DNOG98, G99 and G100
What changes on a UK solar or battery project.
SOLAR DESIGNSolar generation estimates
Why orientation, pitch, location and shading move the number.
BATTERYkW vs kWh
Power and capacity solve different parts of the problem.
ECONOMICSCommercial solar ROI
The assumptions behind payback.
EXPORTSEG explained
Eligibility, suppliers and why there is no universal rate.
VAT / HOME ENERGYVAT on installed solar and battery storage
Current HMRC treatment and the temporary zero-rate period.

Which grid route applies?
See how G98, G99 and G100 relate to connections, export limitations and system controls.
What should you compare?
Explore solar generation assumptions, inverter and module options, battery capacity in kWh and power in kW.
What happens beyond installation?
Read about commercial project economics, SEG export arrangements, VAT rules and the handover documents to retain.
CONNECTED ENERGY SYSTEM
Move between the parts of the system without starting over.
Solar generation, storage, EV charging and grid constraints affect each other. Use these routes to keep the project connected.
ASK A PROJECT QUESTION
Need an answer for a specific site?
Guides can explain the principles. A project conversation can deal with the roof, load, equipment, tariff and grid constraints that are specific to your site.
