How to choose solar panels for your home - comparing prices and manufacturers
Solar energy — the fastest way to reduce utility bills and increase the energy independence of a private home. However, the range of modules is so wide that it is easy to get confused. In this article, we explain step by step how to calculate the power requirement, evaluate the technical parameters and choose a brand, and also provide current prices for Odessa. The link to the service установка солнечных батарей под ключ цена will help you navigate the installation costs.
1. Calculation of consumption and required power
Start by analyzing the electricity meter data for the last year. Add up all kW·h and divide by 12 — this is the average monthly consumption. Next:
- Divide the average by 30 to find out the daily need.
- Multiply the result by 1.2 — reserve for seasonal peaks.
- Divide by the average daily generation of 1 kW of photovoltaic modules in your region (for Odessa — 3.5 kW·h).
For example, at 500 kW·h/month the formula gives 6 kW of installed capacity.
2. Technical parameters to look at
- Efficiency. The higher it is, the less area the system takes up.
- Temperature coefficient. Voltage drop for every °C exceeding 25 °C. A good indicator — ≤0.34 %.
- Degradation. Market leaders claim no more than 0.5 % per year.
- Resistance to PID and LID — potential-induced and light degradation.
3. Price and Brand Comparison (May 2025)
| Brand | Model | W | Efficiency % | Price UAH/W |
|---|---|---|---|---|
| Jinko Solar | Tiger Neo N-type | 435 | 21.8 | 14–15 |
| Trina Solar | Vertex S | 425 | 21.3 | 13–14 |
| Canadian Solar | HiKu6 | 410 | 20.9 | 12–13 |
| JA Solar | JAM54S31 | 415 | 21.0 | 12–13 |
| Risen Energy | RSM40-8 | 400 | 20.5 | 11-12 |
Certificates and warranties
Check for IEC 61215/61730 certificates, fire safety protocols, and warranties: 12 years for the product and 25-30 years for maintaining at least 80% of the initial capacity.
4. Total budget and payback
In addition to the modules, you will need an inverter, cables, mounting hardware, and safety automation. In 2025, a complete 6 kW kit will cost about 4,200 USD. For a "green" At a tariff of 0.16 €/kWh, the system generates 9000 kWh/year and returns the investment in 4-5 years.
Example: Selling surpluses gives about 1440 €, and saving on own consumption — another ≈500 € every year.
5. Documents and connections
To receive payments under the «green» tariff, submit an application to Oblenergo, technical conditions and equipment certificates. After installation, call a network representative to inspect and seal the bidirectional meter.
6. Turnkey installation
The correct angle of inclination, high-quality waterproofing of fasteners and competent cable cross-section can increase annual generation by 8-12%. Professional companies provide a commissioning certificate, a warranty package and service within 48 hours.
Choosing solar panels is a balance between performance, price and brand reliability. Careful calculation and professional installation reduce the payback period and guarantee trouble-free operation for decades. Take the first step today - order a consultation, and specialists will prepare a personal project, select equipment and put the station into operation within one week.
