10KW Rooftop Grid Tie Power System, Moldova

1、 Project background and market environment

Moldova, as an emerging market in Eastern Europe, has seen a significant increase in demand for renewable energy in recent years. In 2022, the government of the country will promote the implementation of photovoltaic projects through tax incentives and grid connection policies, leading to a surge in demand for efficient and stable solar energy systems from households and commercial users. PWSOLAR, with its modular design and localized service advantages, has become one of the main suppliers of distributed photovoltaic solutions in Moldova. Its 10kW Grid Tie system is designed specifically for small and medium-sized commercial facilities, using 500 watt half cell solar panels to achieve maximum power generation efficiency under limited roof area.

2、 Technical solutions and core components

500 watt half solar panel technology

Adopting n-type TOPCon battery technology, the conversion efficiency reaches 24.43%, which is more than 15% higher than traditional P-type components.

Half piece design reduces hot spot effect, extends component lifespan to over 30 years, and is suitable for the climate conditions with large temperature differences in Moldova.

Lightweight structure (weight ≤ 22kg) simplifies installation process and reduces roof load-bearing requirements.

System Architecture and Intelligent Management

The inverter supports MPPT tracking, ensuring a power generation efficiency of over 90% even in cloudy weather.

Integrated IoT monitoring platform, providing real-time feedback on power generation data and supporting remote fault diagnosis.

The lightning protection and overload protection design complies with the IEC 61730 standard to ensure the safe operation of the system.

3、 Project benefits and user feedback

Economic performance

The daily average power generation of the 10kW system is about 45kWh, with an annual power generation of 16425kWh, which can cover 80% of the daytime electricity demand of small and medium-sized supermarkets.

The investment payback period has been shortened to 4.8 years (calculated at a local electricity price of $0.12/kWh), which is 1.2 years shorter than traditional systems.

User Case

After the installation of a chain restaurant in Chisinau city, the annual electricity expenditure decreased by $12000, while receiving a government green subsidy of $3500.

User feedback: "The system can still generate electricity stably in winter, and the monitoring platform helps us optimize the electricity consumption period, further reducing costs

4、 Market competitiveness and expansion strategy

Localized service network

Set up 3 service centers in Moldova, providing 48 hour on-site response and shortening the after-sales cycle to 60% of the industry average level.

Collaborate with local power companies to develop a "photovoltaic+energy storage" package to address power grid fluctuations.

differentiated advantage

The 500 watt component reduces the cost of brackets and wiring, and the total system cost is 8% lower than products of the same power.

Provide a 15 year product warranty and a 25 year linear power guarantee to enhance customer confidence.

5、 Challenges and Future Prospects

policy risk

In 2023, Moldova will adjust its photovoltaic subsidy policy and maintain price competitiveness through technological upgrades.

Technical iteration direction

The plan is to launch 630 watt double-sided modules in 2024, with an expected increase in power generation of 12%, suitable for agricultural photovoltaic integration projects.

The PWSOLAR 10kW Grid Tie system has set a benchmark in the Moldovan market with efficient components and localized services. In the future, through technological innovation and policy coordination, it is expected to further consolidate its market share in Eastern Europe. AI-generated

There are differences in parameters among different manufacturers, so we will maximize the optimization of solar panels. At the same time, as time and technology continue to update, we believe there will be more 500 watt solar panels with different sizes, and even smaller ones.

Our most direct goal is to maximize the installation of solar panels on the roof, meet users' higher power loads, provide users with a better user experience, and save electricity bills for users.
