Check the monitoring app against a comparable day, because a healthy system shows generation that tracks the weather and season rather than sitting flat. A sustained shortfall against similar days earlier in the year is the clearest signal of a fault. An inverter warning light, a tripped isolator, or one string producing far less than another points to something specific.

The system stops generating until the inverter is repaired or replaced, because it converts panel DC output into AC electricity the house can use. Inverters are the component most likely to need replacing during the life of a system, and carry their own manufacturer warranty separate from the panels. A replacement is usually fitted without altering the array.

Rarely, because rainfall clears most dust and pollen from panels set at a normal roof pitch. Cleaning becomes worthwhile where panels sit at a shallow angle, under overhanging trees, near agricultural dust, or where droppings and moss build up along the lower edge. A lasting drop in generation the weather does not explain is a better prompt than a fixed schedule.

No, not unless the system has been configured for backup, since a standard grid-tied inverter shuts down during an outage to protect anyone working on the network. Backup needs compatible equipment, usually a battery with an emergency power supply function and a gateway that isolates the property from the grid, and it normally runs selected circuits rather than the whole house.

Yes, most modern home batteries can be scheduled to charge from the grid during off-peak hours on a time-of-use tariff. The battery then covers the expensive peak evening period from stored electricity, and in winter carries a household through days when generation is low. Charging windows are set in the app and adjusted as rates change.

No, most domestic solar and battery systems run well on a standard single-phase supply. Three-phase becomes relevant for larger arrays, high-power EV charging, and farm or commercial installations. Single-phase properties are limited to 3.68kW of inverter output under G98, and anything above needs G99 approval rather than a supply upgrade.

Yes, adding a battery usually reduces export payments, because electricity stored for later use at home is no longer sent to the grid. That is generally worthwhile, since electricity a household avoids buying is worth more than most export rates. A battery does not remove eligibility, and surplus beyond what it holds is still exported and paid for.

Yes, in many cases, provided there is suitable roof space and the existing inverter has capacity for the extra input. Adding modules can require a larger inverter, an additional inverter or micro-inverters, and going past the originally approved capacity means a fresh notification to the network operator. Matching new panels to older ones is rarely practical, so a separate string is often cleaner.

Not usually, though it depends on the age and condition of the existing board and whether there is a spare way for a dedicated solar circuit. Older boards without RCD protection, or ones already full, may need upgrading so the installation complies with BS 7671. This is assessed at survey and included in the quotation rather than raised later as an extra.

Yes, fitting bird protection during the original installation costs less and causes less disruption than adding it afterwards. Mesh clipped around the panel edges stops pigeons nesting in the gap between the modules and the roof covering, where droppings and nesting material block gutters. Retrofitting means bringing scaffolding back, so it is worth deciding at quotation stage.
