If you’re considering solar panel installation for your home, one of the first and most important stages is the solar feasibility assessment. Before any detailed design work, structural surveys or installation dates are discussed, your chosen solar installers need to establish whether your property is suitable for solar and what system is likely to deliver the best results.
At SolarTherm UK, our solar feasibility assessments are designed to provide homeowners across Essex, Kent, Suffolk, Hertfordshire and the wider South East and East Anglia regions with clear, professional guidance. This stage helps us understand your property, energy usage and lifestyle so we can recommend a tailored solar solution that maximises savings and long term performance.
In this guide, we’ll explain exactly what happens during a solar feasibility assessment and why it’s such a crucial part of the solar installation process.
What Is a Solar Feasibility Assessment?
A solar feasibility assessment is the initial stage of planning a solar panel installation. It allows our solar specialists to determine whether your property is suitable for solar energy generation and identify the most effective system configuration for your needs.
Unlike the later technical survey, which confirms roof structure and installation requirements, the feasibility assessment focuses on:
- Property suitability
- Roof orientation and available space
- Potential solar generation
- Household electricity consumption
- Future energy requirements
- Battery storage suitability
- Return on investment
The goal is to create an initial system design that reflects how you actually use energy, rather than simply fitting as many panels as possible onto your roof.
Why Is a Feasibility Assessment Important?
Every home is different. Two neighbouring properties may have identical roofs but completely different energy demands. One family may be home all day using electricity continuously, while the other may only consume significant energy during the evening.
A thorough feasibility assessment ensures your solar installation is designed around your household’s specific requirements.
This helps to avoid:
- Oversized systems that take longer to pay back
- Undersized systems that don’t match property consumption
- Poor battery sizing
- Unrealistic generation expectations
- Missed opportunities for future expansion
At SolarTherm UK, we believe successful solar panel installation starts with understanding the customer first.
On Site Assessment or Remote Solar Survey
Depending on the property and available information, you can choose for one of our solar specialists to visit your property or carry out a remote survey.
Attend Your Property
An onsite visit allows us to assess roof orientation and pitch, potential shading, available installation space, consumer unit location and property layout. This approach provides valuable real world insight into the property’s suitability for solar energy.
Carry Out a Remote Survey
Many feasibility assessments can also be completed remotely using satellite imagery, aerial mapping software and roof measurement tools. Remote surveys can often provide an accurate starting point while allowing homeowners to receive initial proposals more quickly.
Whether completed remotely or in person, the objective remains the same: establishing whether solar is suitable and designing the right system for your needs.
Understanding Your Energy Usage
One of the most important aspects of any solar feasibility assessment is analysing your electricity consumption. Many homeowners assume solar design is based solely on roof size. In reality, energy usage is equally important.
Our solar specialists will typically review:
- Recent electricity bills
- Annual electricity consumption
- Seasonal usage patterns
- Peak demand periods
- Daytime versus evening consumption
Understanding these factors allows us to recommend a system that delivers meaningful savings while maximising self-consumption of generated solar energy.
Looking Beyond Your Current Electricity Bill
A good solar design should not only reflect how you use energy today, but also how you may use it in the future. During the feasibility assessment, we’ll discuss lifestyle factors such as:
- Electric Vehicles: if you’re planning to purchase an EV, your electricity demand may increase significantly. Future proofing your solar panel installation can help support vehicle charging while reducing reliance on imported grid electricity.
- Working From Home: many households now consumer more electricity during daylight hours. This often increases the value of solar because more generated energy can be used directly within the home.
- Home Extensions: planned property extensions may affect roof space or future energy consumption. Considering these plans early helps ensure your solar system remains suitable for years to come.
- Heat Pumps: if you’re considering switching to renewable heating in the future, this can have a major impact on electricity demand and system sizing.
Creating the Initial Solar Design
Once the property assessment and energy analysis are complete, our specialist will create an initial solar system design. This design typically includes:
- Recommended panel quantity
- Estimated system size
- Expected annual generation
- Battery storage recommendations
- Estimated savings
- Environmental benefits
- Indicative return on investment
The design aims to balance available roof space, budget considerations, household energy demand and long term financial returns. As experienced solar installers, SolarTherm UK focuses on designing systems that provide genuine value rather than simply maximising panel numbers.
Battery Storage Considerations
Battery storage has become an increasingly popular addition to modern solar installations. During the feasibility assessment, we’ll determine whether battery storage is likely to benefit your household.
Factors considered include:
- Evening electricity usage
- Time of use tariffs
- EV charging requirements
- Energy independence goals
- Budget
A properly sized battery can significantly increase the amount of solar energy used within your home, helping reduce reliance on imported electricity.
What Happens After the Feasibility Assessment?
If the proposed design meets your requirements, we’ll provide a detailed quotation outlining the recommended system. Once accepted, the next stage is a detailed technical survey where we confirm:
- Roof condition
- Structural suitability
- Wind loading
- Roof loading calculations
- Electrical infrastructure requirements
- Final installation design
This additional stage ensures that the proposed system can be safely installed and complies with all relevant industry standards.

Frequently Asked Questions
Not always. Many properties can be assessed remotely using aerial imagery, roof measurements, photographs, and energy usage data. However, some homes may benefit from an on-site assessment.
Providing a recent electricity bill, details about your household energy usage, and information about future plans such as EV charging or heat pumps helps us create a more accurate solar design.
Remote assessments can often be completed within a short timeframe, while on-site visits typically take between 30 and 90 minutes depending on property complexity.
Yes. Based on your energy consumption and the proposed system design, we can provide estimated savings and projected financial returns.
No. The feasibility assessment is an initial suitability review. Final confirmation takes place during the detailed technical survey, where structural and installation requirements are fully assessed.
