SSEN and your Flackwell Heath and Wooburn Green connection
The distribution network operator (DNO) for Flackwell Heath and Wooburn Green is Scottish and Southern Electricity Networks (SSEN), which runs the Southern England licence area.
G98 is the simple route. If the inverter, plus any battery, stays at or under 3.68kW per phase, SSEN only has to be told within 28 days after the system is commissioned.
Larger systems go through G99 instead, applied for before installation. On timing: SSEN says it can take up to 45 working days to issue a quotation for a generation connection above 3.68kW per phase and up to 50kW.

Heat pumps and EV charging in Flackwell Heath and Wooburn Green
A heat pump in Flackwell Heath and Wooburn Green

Charging an EV in Flackwell Heath and Wooburn Green
Summer is where a car earns its place. In July, 12 panels in Flackwell Heath and Wooburn Green make about 780 kWh, against roughly 70 kWh a typical home uses in daylight that month on our calculator's typical-use settings, so there is surplus a smart charger can put into the car instead of exporting it.

What does a typical solar system cost in Flackwell Heath and Wooburn Green?

Which DNO covers Flackwell Heath and Wooburn Green, and what does it need from me?
Scottish and Southern Electricity Networks (SSEN) covers Flackwell Heath and Wooburn Green. A home system of up to 3.68kW per phase is notified to SSEN within 28 days of commissioning under G98, and nothing waits on approval. Larger outputs need a G99 application before work starts. SSEN says it can take up to 45 working days to issue a quotation for a generation connection above 3.68kW per phase and up to 50kW.
What happens to the solar I do not use in Flackwell Heath and Wooburn Green?
Around £658 a year at 12p per kWh, for the roughly 5,481 kWh a 12-panel system in Flackwell Heath and Wooburn Green exports with typical use. Rates vary by supplier and some need their own tariff; the export rates table is dated and sourced.
How much solar does Flackwell Heath and Wooburn Green get in December?
December is the low point: about 220 kWh from a 12-panel system in Flackwell Heath and Wooburn Green, on PVGIS data, rising to 780 kWh in July. From November to February the same system makes about 1,100 kWh in total, which is why a battery charged off-peak does more of the work in winter.
