Our engineering checklist
Every proposal is reviewed against the same technical checklist we use internally on our own projects. Not a quick read — a structured audit.
System sizing
- Proposed peak power (kWp) versus real consumption
- Panel count, wattage and brand
- DC/AC ratio and inverter oversizing
- Orientation, tilt and string design
- Shading analysis (chimneys, trees, buildings)
- Roof suitability (weight, fixings, tile type)
Inverter, battery and protections
- Inverter brand, model and tier · service network in Spain
- Battery: usable capacity (kWh), depth of discharge, guaranteed cycles
- Realistic self-consumption strategy (with and without battery)
- DC/AC protections, breakers, RCDs and surge protection
- Readiness for EV charger, air-source heat pump, pool heat pump
- Monitoring and remote access
Legalisation and economics
- Legalisation under RD 244/2019 (CAU, technical report / memoria técnica, boletín)
- Surplus compensation and virtual battery scheme
- Price €/kWp versus the Costa Blanca market
- Warranties: product, performance, workmanship, installer
- Estimated payback with and without subsidies
- Hidden costs: scaffolding, civil works, consumer unit upgrade, VAT, paperwork
How the review works
1 · Upload
Send the proposal PDF and a couple of basic details about the property.
2 · Engineering analysis
Our engineers review sizing, equipment, protections and legalisation.
3 · Market comparison
We benchmark €/kWp, equipment and conditions against the real Costa Blanca market.
4 · Risk detection
We flag omissions, oversizing, undersizing and small-print traps.
5 · Global Report
You receive a professional PDF by email with findings, risks and a clear recommendation.
The Global Report — the core of the service
After the review you receive a professional Costas Solar PDF. Not a set of loose notes — a structured document you can take to any meeting, use to compare quotes side by side, or keep on file.
1. Executive Summary
One page: what is proposed, what we recommend and why. Designed to be read in 2 minutes.
2. Overall Recommendation 🟢 🟡 🔴
Clear traffic light: proceed with confidence, clarify or renegotiate, or review carefully before signing.
3. Technical Assessment
Sizing, inverter, DC/AC ratio, protections, shading and coherence with real household consumption.
4. Financial Assessment
€/kWp versus the market, expected self-consumption, payback, warranties and hidden costs.
5. Equipment Review
Proposed brands and models, tier ranking, datasheet check and after-sales service availability in Spain.
6. Hidden Risks
Legalisation, RD 244/2019, missing protections, cabling, insurance and compatibility with future upgrades.
7. Market Comparison
Typical price ranges and configurations on the Costa Blanca for similar homes.
8. Questions to Ask Your Installer
A list of specific, technical questions to bring to your next meeting with the company that quoted you.
9. Final Recommendation
A clear next step: sign, renegotiate specific points, or request an alternative proposal.
The Global Report is yours. Use it with us, with the original installer, or with any other company.
When does a second opinion help?
You received several quotes with very different prices and don't know which to pick.
The proposal includes a battery and you're unsure if it's worth it.
You plan to add an EV charger, air-source heat pump or pool heat pump later.
You suspect the proposed power is oversized or too tight.
You don't fully understand the line items or technical terms.
You want to make sure the installation is properly legalised.
Our approach
We do not work to confirm or dismantle another company's proposal. We work for the homeowner.
If the proposal is solid, we say so clearly. If we find problems, we explain them with technical criteria — not opinions.
We are not tied to any panel, inverter or battery brand. Equipment is recommended by performance and after-sales service, not by commission.
