Solar and heat pumps cut energy use in Chisinau home
A resident of Chișinău, Dinu Bubulici, has significantly reduced household energy dependence by combining solar generation, insulation, and heat pump systems in a single integrated setup.
His home, covering around 75 square meters, is equipped with an 8 kW photovoltaic system that generates approximately 8,000 kWh of electricity annually. According to him, improved thermal insulation plays a decisive role in overall efficiency.
In addition to solar panels, he uses heat pumps that transfer thermal energy depending on seasonal needs, providing heating during winter and cooling during summer by reversing operational flow.
Bubulici estimates that his household consumes roughly 8,000–9,000 kWh per year, with photovoltaic production covering around 90% of total electricity needs, while the remaining 10% is drawn from the grid.
Speaking on Radio Moldova, he noted that energy recovery systems remain relatively uncommon due to cost and complexity, though DIY approaches can partially mitigate expenses.
From his experience, he argues that the most effective strategy begins with thermal insulation of walls, ceilings, and floors, which reduces heat loss before investing in generation systems. He emphasizes that solar panels should be considered a complementary solution rather than the primary fix for inefficient buildings.
