SOLAR PANELS SAVING IN YOUR HOME! PUPILS FROM SCHOOL OF ECONOMICS ŠIBENIK

* SOLAR ENERGY for heating water and heating support protects the environment, and also helps in saving * Modern heating technique and solar heating technology allows efficient use of sunlight even at low temperatures and low light levels * However, new construction or modernization - in each case you should consider the solar system

SOLAR PLANTS *They can be mounted on the roof (vertically/ horizontally) or on the depending on the construction and purpose * The largest consumers of electrical energy in the household are thermal consumers (boilers) * Benefits: - Full coverage of hot water consumption in the summer months - Partly (up to 60%) reduces the energy consumption of hot water and heating

* Main areas of use of modern solar plants - Drinking water heating - heating support

TECNICAL SOLAR PLANT *It warms water and supports heating with 60% of electricity savings? * Solar collectors take sunlight and convert it into heat that goes into the hot water reservoir * If there is not enough solar energy, the heating coil in the reservoir heats water with electric power * Usually used for home use or smaller buildings

SOLAR HOUSE FOR ENERGY SAVING SOLAR HOUSE FOR ENERGY SAVING * Construction with energy saving system for heating of approximately 85% (per m² living space per year is kwh savings per m²) * Characteristics: -big building -passive use of solar energy? -massive construction of houses for storing energy (roof or basement) -more expensive version of construction

CALCULATION EXAMPLE OF SAVING WITH SOLAR PANELS CONSTRUCTION: a school area of ?? 600m² CONSUMPTION OF EL. ENERGY: 8790kw (monthly 733kw; daily 24kw) COST: 3850 € per year

BY INSTALLING THE SOLAR PANELS INVESTMENT AND MONEY RETURN ARE THE FOLLOWING: SOLAR PANELS: 22 pieces of strength 250w EFFICIENCY OF PANELS ON AVERAGE: 1 panel produces per day 1,125kwh x 22pcs = 24kwh SETUP PRICE - PURCHASE OF PANEL: 500 € / pcs -500 x 22 = 11,000 € MONEY RETURN: 11,000 / 3,850 = 2.86 ≈3 years? CONCLUSION: Solar energy has never been more accessible and profitable
