Solar Panels for Holiday Homes
Resource Highlights:
Solar panels can reduce holiday home running costs by powering the property when it’s occupied and when it’s empty.
When the home is unoccupied, unused solar electricity may be exported to the grid and you may be paid by your energy provider depending on tariff and eligibility.
Battery storage can help if guest use is mostly evenings, but solar-only can still be worthwhile.
Monitoring is important for holiday lets, it helps you check performance remotely.
Why it can be a smart upgrade, even when you’re not there
Holiday homes have a unique energy pattern. The property can sit empty for days or weeks, then suddenly be used heavily when guests arrive. That makes running costs unpredictable, and it’s exactly why solar panels can be such a practical upgrade.
A well-designed solar PV system can:
reduce day-to-day running costs
support a more energy-efficient letting property
and importantly, generate value even when the property is empty, because surplus electricity can be exported back to the grid depending on your tariff and setup.
This guide explains why solar works well for holiday lets, how “earning when you’re not there” works in practice, and what to consider before installing.
Why install solar panels on a holiday home?
Reduce your running costs (even with guest usage)
Holiday lets often include electricity within the rental price. That means every unit used comes off your margin. Solar helps reduce the amount you buy from the grid, especially during daylight hours.
It can also help with:
hot tubs, pumps and filtration running during the day
electric showers and cooking loads during guest stays
heating and ventilation systems that run intermittently
Earn value when the property is empty
This is one of the biggest advantages for holiday homes.
When the property is empty, your electricity use is often low. A solar system may still generate electricity in daylight. If that energy isn’t being used on site, it can be exported to the grid.
Many energy providers offer export payments for surplus electricity, depending on your tariff and eligibility.
This is one of the biggest advantages for holiday homes.
When the property is empty, your electricity use is often low. A solar system may still generate electricity in daylight. If that energy isn’t being used on site, it can be exported to the grid.
Important note: export payments and eligibility vary by supplier, metering setup and scheme requirements, so it’s best to check your tariff and ensure the system is installed and documented correctly.
Improve your property’s sustainability appeal
Many guests actively look for accommodation with better sustainability credentials. Solar doesn’t replace good insulation or efficient heating, but it’s a visible, practical step that supports greener holidays.
Remote monitoring gives you peace of mind
For holiday homes, monitoring is a major benefit. It allows you to:
check the system is generating properly
spot faults early
confirm performance remotely

What to consider before installing solar on a holiday home
Roof suitability and shading
Holiday lets are often in rural or coastal areas where shading from trees, chimneys or neighbouring buildings can be a factor. A survey will confirm the best layout.
Your electricity tariff and export setup
If the goal includes earning from export when you’re not there, it’s important the system is:
installed by a properly accredited installer (where required for tariff registration)
commissioned correctly
supported by the correct documentation
paired with suitable metering and export settings
Maintenance and access
Solar is low maintenance, but holiday homes benefit from:
a system design with safe access in mind
monitoring alerts
an aftercare plan so issues can be resolved quickly
Guest experience and safety
Equipment placement matters. Inverters and batteries should be:
installed in suitable, ventilated areas
kept tidy and protected
clearly explained at handover so there are no guest concerns
Important Note: Export payments depend on energy supplier, tariff, metering setup and eligibility. Always check your provider’s terms and confirm installation requirements during survey.
Simple overview
If you want the simplest approach, follow this order:
Assess roof suitability, shading and usable space
Review your holiday home’s energy pattern (occupied vs empty periods)
Decide solar-only or battery-ready setup
Confirm export arrangements and metering requirements
Install, commission and set up monitoring
Use real data to decide whether battery storage is worth adding later

Frequently Asked Questions
Yes. Solar can still generate electricity when the property is empty, and surplus may be exported to the grid depending on your tariff, which is one of the reasons holiday homes can be well suited to solar.
Not always. Solar-only can still be worthwhile. A battery can be useful if guest electricity use is mostly evenings or if you want to store more of the daytime generation.
Most systems are discreet. Monitoring is handled through an app and equipment is installed in appropriate locations. If you want, you can add a simple “this property is solar powered” line to your welcome pack.
Yes. Modern systems usually include monitoring so you can check generation remotely and spot issues early, which is particularly useful for holiday homes.
