Case Study : 10Ton Hotel hot water supplying by solar photovoltaic and heat pump
发布时间：2025.10.20Case Study : 10Ton Hotel hot water supplying by solar photovoltaic and heat pump
Villa Hotel in Brazil inport EVE photovoltaic and heat pump hot water project system to supply 10 tons 60-70C hot water per day for its hotel rooms , saving more than 60% power energy is the most top primiary choice for our customers. 
The advantage of this photovoltaic and heat pump hot water project system as follows :
- High efficiency solar PV with UL/CE/TUV certificate to get electricity from solar photovoltaic diractly
- This power support heat pum directly to DC invert to engineer this system without any others power storage and invert
- Pressurzied enameled water tank is the necessary parts
- digital controlers can protect all process and details for this whole system
- Commercial DC inverter heat pump hot water project system is able to reach COP more than 3.0 to save lots of cost for our customers
- This system can supply 10tons 60-70 degree hot water per day
Cost comparation and calculation as follows :
- If only electricity power , this 10 tons 55 degree hot water need power 525Kwh
- If this hotel open the whole year as 360 days , the total power comsuption will reach 189000KWH, the cost for electricity will be 0.8CNY / kwh
- The heat pump COP can reach 3.0 - 4.0 in our commercial heat pump system , the this will only take 63000kwh
- The solar photovoltaic panel power capacity only need 20kw , the cost is 1.5CNY/w , the total cost is about 30000CNY. The heat pump invest will be 5500CNY/ton, total cost will be 55000CNY.
This sheet cost-calculation with regards to 189000kwh eletricity power and transfer to heat pump is 63000kwh
