How high should the electricity bill be before considering solar?
There is no single bill threshold for every home or business. Daytime demand, roof area, electrical conditions and the owner’s objective should be reviewed together before sizing.
SOLAR ROOFTOP
Solar Rooftop for Homes, Businesses & Industry
Solar rooftop systems for Surin and nearby provinces, sized from electricity bills, usage timing, electrical conditions, roof area and the actual project goal.
CHALLENGE
Start from the problem that actually needs solving
The same monthly bill does not mean the same solar size. Usage timing, roof conditions, shading and electrical infrastructure change the right design.
Best suited to: Homes, retail, hotels, SMEs, factories, warehouses and institutions
ENGINEERING APPROACH
Collect the right data before selecting equipment
- Review electricity bills and daytime/nighttime usage before sizing.
- Check roof area, orientation, shading, structure, electrical system and equipment locations.
- Compare On-grid, Hybrid or Off-grid against the project objective and constraints.
- For businesses, PPA and monitoring can be considered as project options.
SCOPE
A practical scope for the first site discussion
- Site survey and data collection
- System sizing and layout
- Electrical and equipment installation
- Testing, monitoring handover and lifecycle planning
OUTCOME
What should become clearer after the site survey
- A system size tied to actual demand
- Clearer options and constraints before investment
- Verified site inputs ready for detailed design and quotation
Equipment, warranty, timeline and pricing are confirmed from verified site information and the final project quotation.
Frequently asked questions
Questions before a Solar Rooftop site survey
Is On-grid or Hybrid more suitable?
On-grid can suit sites focused on using daytime solar, while Hybrid may suit projects that also need storage or selected backup. The final choice depends on the real site and budget.
What should I prepare before a survey?
Recent electricity bills, roof photos, electrical-board photos, location and the period of highest usage are useful. You can still start with whatever information you already have.
Will the meter or utility process need to change?
It depends on the system type and site conditions. The team checks whether the proposed system requires meter work, documentation or coordination with the electricity authority before implementation.
When does the roof need additional structural checking?
Older roofs, roofs with leaks, corrosion, visible deflection or unknown structural information should be checked before finalising panel locations. Photos alone may not be enough.
