Smart energy management With the EnergyManager PV smart, Hoval has perfected the combination of heat pump and PV system in a wonderfully innovative way, without any additional hardware, interfaces or extra costs. This system boosts solar selfconsumption by up to 10%.
Storage for power from PV systems However, battery storage devices for solar power are relatively cost-intensive and often take a long time to pay for themselves. In some countries, government subsidies ensure that customers do not bear the brunt of the costs. Nevertheless, the life cycle assessments for many rechargeable batteries still yield mixed results.
