FENNOR / SOLAR FAQ & ADVICE
Will solar work on your roof? What does a battery add? How much power will you still buy? Fennor explains the choices in plain language and helps you take the next step for your own property.
A READING ROOM FOR BETTER DECISIONS
Fennor assesses the roof before agreeing the array and explains any repair work that needs to come first. That helps avoid paying to remove and reinstate panels for near-term roof work.
We compare suitable roof faces for orientation, shading and time-of-day output. You see why a split layout may suit your electricity use differently from panels on a single slope.
Fennor explains generation, direct self-use, export, tariffs and the costs included. We also show what lower self-use does to the estimate, so your decision does not depend only on the most attractive scenario.
Not necessarily. Extra generation may be exported rather than used on site. Electrical limits, roof constraints and the marginal cost also affect the comparison.
We compare usable energy, charge/discharge power, inverter compatibility, warranty conditions and how you intend to use storage. You get a like-for-like explanation, not just a bigger capacity number.
Fennor assesses the battery, diverter and charger together. The installation team configures the agreed priorities and shows you how they share surplus; separate apps alone do not establish compatibility.
At handover, we take you through the installed equipment and controls, arrange the relevant electrical and grid records, and explain warranties and who to contact for support.
Tell us about a planned EV, heat pump, roof work or extension. We explain which future changes the proposal allows for and which would require further design, equipment or cost.
A GOOD SOLAR CONVERSATION
Start with the bill and the questions you have. Fennor uses your annual usage and, where available, its timing to assess the opportunity. We include your future plans and explain the next survey and proposal steps—you do not need to arrive with a finished design.

A QUESTION WE CAN WORK THROUGH WITH YOUYOUR PROJECT WITH FENNOR
We explain the choices, the work involved and what happens next, so you can decide with a clearer picture.
kWp describes nominal panel capacity, kW is power at a moment and kWh is energy over time. We use your proposed equipment to explain the difference, so inverter power and battery storage are not treated as the same figure.
We explain expected generation, direct use, export and tariffs alongside the system price. The estimate reflects the assumptions about your routine, and we show why a change in daytime use could affect the result.
Tell us about planned repairs or anything that concerns you. We identify the condition, structural and shading checks needed, then explain access, cable routes, weatherproofing and maintenance in the proposed installation.
A SIMPLE START
MORE WAYS WE CAN HELP
SUPPORT FOR THE WORK YOU HAVE IN MIND
These are the relevant funding options to discuss with Fennor alongside your project. We explain the full price, the support that may apply and the steps before you commit.
Reviewed · Guidance, not an eligibility decision.
Grant support
Up to €1,800
Support is based on the installed panel capacity. With a separately eligible €600 battery grant, the combined standard maximum is €2,400.
Grant support
€600
Flat-rate support for an eligible battery of at least 5 kWh. A larger battery does not increase this grant.
Grant support
Up to €9,000
An eligibility-based route: up to €8,400 solar PV plus €600 for an eligible battery. It replaces—not adds to—the standard PV rate.
USEFUL ANSWERS
Plain language. No pressure to have it all figured out.
Yes, PV can generate in diffuse daylight, usually less than in strong sunlight. Weather, season and shading affect output. We explain those factors in the site-specific estimate.
No. Other directions can work with different generation patterns. We establish the site assessment needed instead of ruling a roof out by direction alone.
Usually not. Imports, standing charges and other charges can remain. We explain the expected balance between generation, use and export using your tariff and routine.
We set out the agreed equipment records, applicable electrical certification, grid-notification evidence, commissioning, warranties and operating guidance. We also explain who will handle your aftercare questions.
We explain both options using your demand, surplus, tariff and equipment compatibility, including whether later expansion is practical. A battery needs a useful purpose, not just a place on the quote.
