In addition to the price of the system itself, you should also include any additional costs such as installationand Council building consents.
Step 1. Open a new tab or window and visit the NIWA Solar View website. Select the planned panel tilt and panel bearing, and generate your SolarView. Once the SolarView is generated, right-click on the 'Download the Typical Meteorological Year Table' button and copy the link. Paste the link into the designated field below. Step 2.
The NIWA Solar View tool is an excellent resource for gathering solar data for a specific location. However, converting that data into an accurate prediction of a typical year's performance for an Off-Grid or Grid-Tied Hybrid system can be challenging.
A 4 kW system consists of between 11 and 14 solar panels, dependent on the size of the panels. Commercial: Commercial sized systems typically start at 10kW (for instance, a small convenience store) and up to 150kW for a large big-box store. The default prices should be considered a rough guide.

On January 7, 2023, the ministry set the ceiling prices at 1,184.90 VND (5.05 cents) per kWh for ground-mounted solar projects, 1,508.27 VND (6.43 cents) for floating solar projects, 1,587.12 VND (. . The government is proposing a tariff of VND671 (US$0.024) per kWh for surplus power from the rooftop solar panels, with a proposed offtake volume of up to 10%. [pdf]
Vietnam’s Ministry of Industry and Trade (MIOT) recently introduced new ceiling prices for solar and wind projects that sell electricity to Electricity of Vietnam (EVN). The ceiling price for ground-mounted solar has been slashed from $0.0709/kWh to $0.0502/kWh, threatening the financial viability of large-scale solar projects.
The ceiling price for ground-mounted solar has been slashed from $0.0709/kWh to $0.0502/kWh, threatening the financial viability of large-scale solar projects. Vietnam’s Ministry of Industry and Trade (MIOT) has set new price ceilings for the so-called “transitional” wind and solar projects.
On 7 January 2023, the Vietnam Ministry of Industry and Trade announced new ceiling prices for solar and wind energy in the country, pursuant to which Vietnam Electricity (“ EVN ”) can now negotiate tariffs in relation to transitional solar and wind energy projects in accordance with Circular 15/2022/TT-BCT (“ Circular 15 ”).
However, the current Vietnamese solar PV market is estimated to be only around 5 MWp, with 80% off-grid applications in rural areas. Solar energy is not yet integrated into political energy development strategies, such as the national Power Development Plan (PDP).
In 2021, the data showed that Vietnam now has 16.5 GW of solar power. This was accompanied by its green energy counterpart wind at 11.8 GW. A further 6.6 GW is expected in late 2021 or 2022. Ambitiously, the government plans to further bolster this by adding 12 GW of onshore and offshore wind by 2025.
Solar energy in Vietnam is available all year round, is rather stable and distributed widely over different eco-geographical areas. Solar energy, especially in the southern and central regions can be used on average 300 days per year. It can be exploited to meet the two main demands: thermal and electrical power (To Quoc Tru, 2010).
