Life is directly linked to the quality of the natural environment and the availability of natural resources. Unfortunately, human influence on the environment is increasing due to mass production, the rapid rate of urbanization, and a growing demand for fossil fuels for energy and transport. According to data from the International Energy Agency, between 1971–2014 carbon dioxide emissions (CO2) have doubled. There is a need for wider penetration of renewable energy sources to achieve the Paris Agreement and Kyoto target of limiting temperature increase. Environmental protection is seen as the most important reason for investing in a renewable energy system. So what can one do to contribute to saving an environment without changing the comfort zone? Where are many small steps to go forward, starting from choosing a friendly way to move to the cities: bike, scooter or public transport. And ending in becoming an energy provider yourself. Some of the ways are more convenient rather than others.
Solar water heating
As written above environmental protection is seen as the most important reason for investing in a renewable energy system. Residential homeowners can consider becoming energy providers having a PV plant on the roof. The only obstacle is the need to invest a lot. The smarter option is to use the renewables for water heating. Probably you have heard about solar thermal systems for water heating, but not heard about PV based technologies. Yes, PV can be used just to heat water and the easiest way to do it is Nectar Sun. Nectar Sun controller uses dedicated solar panels (PV) to heat water and to save money. When the water hits its temperature set point the panels are deactivated. If there is not enough sun, it switches to local electricity. The grid power is kept on a separate circuit – so the panels never connect to the grid. Nectar Sun controller is able to connect to most electric and hybrid water heaters available for household use. The device connects directly to the heater, without changing the existing electrical wiring. No pipes, valves, pumps or other additional equipment. It is easy to maintain, install and use. Simple, sustainable and cost-effective technology for ones who want to invest in renewable energy and reduce their usage in a better way. It has a mobile application, so it can be controlled for a comfortable and smart living.
Solar costs have declined significantly, and are at their lowest point in over 30 years. Solar is now more affordable than ever and advances in technology have improved system quality and design. But we are not going to discuss advantages and disadvantages of all the options a one has. Our aim is to inform you have a choice. So make it smart - go green one way, or another.
The latest innovation in photovoltaic water heating is Nectar Sun - the simplest PV based system made for water heating. The Nectar Sun controller is responsible for converting cost-free solar energy to free hot water. It is a cost-efficient way to save up to 70% off hot water bill. It is a fully automated system that can be installed in a couple of hours - no cables, pipelines or frequent maintenance. Thanks to full bridge technology, which allows to tune up to almost all electric and hybrid water heaters. The Nectar Sun is the only solution without a need to disassemble the water tank or change the immersion heater. Just plug & play. It is suitable to work with all electric and hybrid heaters up to 300 liters with 2.0 kW of usable solar capacity. Eco-friendly design helps to minimize the space, materials, and harm of utilization. Also, it saves you valuable time during installation. Same for the commissioning with its user-friendly mobile application.
The price drop
A few years ago no one could imagine what PV systems might compete with solar thermal. Due to the fast development of technologies and the rapid drop in prices, now PV based water heating solutions are even cheaper than thermal. Because of it, the investment in Nectar Sun system might pay back in 3-5 years. The Nectar Sun system is a result of years of research and practice combined. This is why it is protected by a 3-year warranty for the Nectar Sun controller and up to 30 years for solar panels (PV).
No permits needed
Nectar Sun controller uses dedicated solar panels (4-8) to heat water and save money. When the water hits its temperature set point the panels are deactivated. If there is not enough sun, it switches to local electricity. The grid power is kept on a separate circuit – so the panels never connect to the grid. That’s why it is a smart way to store your energy without any permits or paperwork needed to install the system. From now on you need only 3 components for modern and sustainable water heating: Nectar Sun controller, PV panels and water heater you already have.
