Roof and daylight survey
The roof covering, structure, usable area, pitch, orientation, shading and safe access are checked before a system is recommended.
Solar PV systems
Solar designed around your roof and energy use.
Generate electricity from daylight, reduce reliance on grid power and create a system that can work with battery storage and EV charging.

Good solar starts with the right checks.
No two properties use energy in exactly the same way. Zeco coordinates the assessment and proposal while suitable installation partners carry out specialist design, electrical and roofing work.

How a solar project is coordinated.
Energy-use review
Recent electricity use and daytime demand help determine an appropriate array, inverter and possible battery size.
Electrical assessment
The consumer unit, cable route, earthing and proposed equipment locations are reviewed by the installation partner.
Design and proposal
You receive a property-specific design with the proposed equipment, estimated generation, assumptions, scope and price.
Permissions and grid process
Planning, building-control and electricity-network requirements are considered for the property and system size.
Installation and handover
The appointed specialists install, test and commission the system, then provide operating guidance and project documents.
Straight answers
Important things to understand before choosing solar.
Daylight, not constant sunshine
Solar panels generate in daylight and can still work in cloudy conditions. Output changes throughout the day and year.
Power cuts and backup
A standard grid-connected solar system normally shuts down during a power cut for safety. Backup operation requires specifically designed compatible equipment.
Battery storage
A battery can store suitable surplus generation for later use, helping you use more of the electricity produced at home.
Electric-vehicle charging
Compatible controls can direct available surplus solar energy to an EV charger, but grid electricity may still be needed.
Maintenance and lifespan
Panels have no moving parts and generally need limited maintenance. Warranty length, degradation and maintenance requirements vary by manufacturer.
Exports and smart meters
Eligibility and payment for exported electricity depend on your supplier, meter, tariff and the documents required by the relevant scheme.
Estimates are not guarantees.
Generation, savings, payback, export income and installation times depend on the property, weather, energy use, tariffs, equipment and final technical design. A calculator or initial conversation cannot replace a site-specific assessment and written quotation.

Solar panel systems for London homes
A useful solar proposal starts with the property—not a standard package. Roof direction, pitch, shade, usable area, household demand and future plans all affect a suitable design.

Aerial mapping tools such as Google's Project Sunroof are built around US coverage and often return no result for UK addresses. For an accurate picture of your home's solar potential—roof space, orientation, shading and expected output—we assess your property directly and provide a written proposal.
What we consider
✓ Roof orientation, pitch and shading✓ Current and expected electricity use✓ Suitable panel and inverter positioning✓ Options for future battery or EV charging
Common questions
Are solar panels suitable for London homes?
Many London homes can use solar PV, but suitability depends on roof space, orientation, shading, structure and any planning constraints.
How many solar panels will I need?
The right number depends on usable roof area, electricity consumption and the output of the proposed panels. It should be calculated for the individual property.
