Como você pode orçar para projetos de energia renovável?

First of all you have to figure out your total load where you want to install the system that can easily be figured out by your electricity bill or you can contact the expert for that, after that you can figure out how much budget you have and how many solar panels you can install and how much will you earn from that system.

It is important to take a systemized approach because any energy related project is not just about energy. It involves more than just the power I need and power I will produce. 1. Define an overall goal. 2. Define stakeholders involved in achieving that goal. 3. Each stakeholder to define what is important to them (this can be values, money, time, etc.) 4. Prioritize the stakeholder needs based on feasibility, interdependence and any other important rankings. 5. Rewrite the goal and be prepared and open to change the goal even if it does not reach the original target set. Ex: Comfort as a driving factor for a hospital or retail space, which may drive a specific type of HVAC system which in turn may define the entry performance potential.

It is also important to consider the cost of component replacement where necessary. For example, for an off-grid solar PV project with backup, it may be necessary to replace the batteries every 5-10 years depending on battery technology.

In addition, you may want to check warranties on the system and system components that you intend to consider or use. It is as important as the integrity of the system itself.

The most economically sound project based on ROI or payback period or other economic indicators may not always be the most environmentally friendly option. Sometimes, a choice may have to be made on a slightly expensive option to align more with the company’s environmental goals.

Key Performance Indicators and the systems required to measure should always be part of your end solution. Without this you can not show what you achieved or did not achieve and more so can not answer Why.

Budgeting for renewable energy projects in South African construction involves detailed planning. Assess the project, estimate costs, and consider resources. Develop financial models and assess risks, securing diverse funding. Create cash flow projections and allocate for contingencies and environmental impacts. Implement monitoring and engage stakeholders. Stay updated on incentives and advancements. This ensures successful execution of renewable energy projects.

This article is unspecific, it needs to be narrower, since budgeting can be in many stages starting from planing, used technology, location, constructing, operating, maintaining, marketing and retiring. Which stage are you concerned about defines your budget. Budgeting may differ dramatically from project to project. There are many factors involved (some of them are fore-mentioned) into this process and they are nonlinearly interacting with each other. Budgeting is not an easy task to be handled in few lines. I suggest to make it narrower, allowing us to be more specific in our opinions and share what we know properly to deliver the utmost benefits.

I have seen many high aspirational goals and targets set only to be crushed when the cost, feasibility or timelines are learnt. This can crush projects. I like to try and keep a focus on Whole Life Value and work in steps to achieve. Rome was not built overnight and trying to go too big all at once can end up being more detrimental than achieving incremental gains in search of the total aspiration.
